This document discusses limitations of the lumen as a unit of measurement for lighting and proposes alternatives or additions. It begins with background on how lumens are defined based on the photopic visual response curve. It notes limitations in using lumens to evaluate non-visual responses and different light needs. The document proposes evaluating sources based on their visible radiant power output or weighting their spectral power distributions by other response curves beyond just photopic. The goal is to better characterize sources for applications like circadian impact, scene brightness, or material damage. It retains using lumens but suggests additional metrics to characterize sources for specific non-visual lighting needs and effects.
The NSF Engineering Research Center for Smart Lighting is developing intelligent controls and autonomous lighting systems that provide high-quality tunable illumination that adapts to human needs and environmental changes to enhance occupants’ performance, health and well-being. We introduce new sensing capabilities that allow lighting systems to detect and respond to changes in their environment, both in terms of a room’s illumination and the activities of its occupants. A key aspect of our approach is occupancy sensing and activity estimation using low-resolution distance sensors, which produce results comparable to cameras while preserving the occupants’ privacy. Knowing the occupants’ locations and activities allows our advanced control algorithms to deliver optimized lighting to any situation with minimal human intervention: “The Right Light, When and Where You Need It”. In addition, lighting will provide increased bandwidth for high-speed data access via illumination-integrated visible light communications. We will also discuss extensions of our smart lighting framework to broader contexts in which rooms react intelligently to their occupants, including advanced cognitive, immersive environments and integration with HVAC systems.

Measuring Light Pollution - How New Technology is Making it Possible. Cindy Foster-Warthen
25 years after the term “light pollution” was coined, we still have a hard time understanding what it is. Measuring it is difficult and metrics to describe it are still being developed. Innovative techniques like all-sky imaging and high dynamic range photography are finally making it possible to accurately measure night sky brightness and glare. International Space Station and satellite imagery is also being used to measure global sky brightness and document trends in its proliferation. This session will demonstrate how to measure different aspects of light pollution and examine the metrics that have been developed to quantify it.

LEDs are finally coming into their own: multiple manufacturers have created solutions using tunable white light for architectural applications. However, these solutions are as diverse as the problems they solve. In order for tunable white to be effectively applied in this wide arena of vertical markets we first need to understand the limitations and capabilities of the technologies and controls, as well as the metrics that describe them. We explore first-hand some application examples in the health-care, retail, and art industries with some award-winning lighting designers to help understand that the best fit may be not be a "one-size fits all".

Currently, there is a popular theory that connects the risk of developing some cancers, like breast and prostate cancer with nocturnal exposure to blue light. This theory is based on the already well-established connection between the shift work and these cancers, as well the connection between the sleep deprivation and cancer development and the anti-carcinogenic effect of the melatonin. In the talk, Alejandro will explain the last results trying to verify this theory. He will also consider other factors that recommend limiting the massive use of white light outdoors at night, as reinforcement of the precaution principle associated to the potential carcinogenic effect of artificial light at night.

Bringing Intelligence to Outdoor Lighting - Which is Better Wired VS Wireles...Cindy Foster-Warthen
As more and more organizations consider lighting upgrades for outdoor lighting, they are met with a unique opportunity to also bring intelligence to their lighting systems by bundling controls along with the LED upgrade. But controls are unknown territory for many decision makers. And with LED lifespans ranging upwards of 20 years, they want their construction or design professional to perform a comprehensive technology assessment before selecting a technology they will be using for the next generation. Today, both wired and wireless options are available in the marketplace, how does the professional make sure which technology is the best for the project? In this session, Rita Renner will explore the benefits of each technology as well as the challenges, then look at ideal applications for each. She will also examine actual case studies where only one control technology was used, as well as examples where both technologies were used together, to illustrate how real project teams made assessments and implemented the best technology platform for their situation.

Day and Night in Building Science and Chronobiology: How the buildings we inhabit could take advantage of daylight—both to keep human occupants comfortable and healthy, and also to optimize energy efficiency. The third event in our series on light.
Natural light helps keep our bodies in tune with the external cycle of day and night, the so-called circadian system, and therefore with the world around us. For many, sunlight is a cue to wake, while darkness leads us toward sleep.
It is important, then, that the buildings we inhabit take full advantage of daylight—both to keep human occupants comfortable and healthy, and also to optimize energy efficiency.
For the third event in our series on light, swissnex San Francisco brings Jean-Louis Scartezzini and Mirjam Münch, from the Solar Energy and Building Physics Laboratory at EPFL, to present their experiences with daylighting research and technology. Their work illustrates possible integration steps toward optimized “Day and Night” lighting environments with respect to energy consumption and human health.
Marilyne Andersen, associate professor in the Building Technology Program of MIT’s Department of Architecture and head of the Daylighting Lab, also joins the discussion with an overview of her efforts to better integrate energy-efficiency and human-responsiveness to daylighting into architecture and design.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

4. Abstract: Lumens and footcandles are measures of light so
often considered critical to lighting design and the energy
efficiency of lighting systems, yet the basis for these units
is also often misunderstood. This seminar reviews the
foundation for the lumen, and in turn footcandles, illustrates
some of the issues in using these measures to evaluate the
performance of lighting systems, and suggests an
alternative method of evaluating spectral effectiveness
for specific applications.
5. Learning Objectives:
Understand how the human body processes visible radiation for different needs,
weighting the spectrum differently for different tasks
Learn about the different photoreceptors in the eye and their spectral sensitivity
Hear how the lumen was originally derived, subsequently modified, applied to all
lighting uses; and is still a unit unsuited for measuring brightness perception,
nighttime visibility, circadian physiological effect, etc.
Be able to articulate why the lumen has a narrow use, and why lighting
professionals need to be conversant in other ways to evaluate the effectiveness of
lighting energy.
See some proposals for modifying the lumen, adding variants on the lumen for
specialized applications, and/or evaluating radiance weighted by spectral response
curves.

17. The lumen is the only SI
unit based on a human
response. It’s watts of
radiant energy in the visible
range, weighted by V-
lambda.
The Lumen was defined in 1931 by the CIE based
on a 2º visual field. It was redefined in 1978 based
on a 10º field, (which effectively adds more blue
content to the weighting of the lumen). The 1978
lumen is almost never used.

43. The Well Building Standard
Ratio of melanopic lux to
photopic lux (M/P)
Use this as a rough guide
only.
CCT is a very poor way to
characterize light sources!
How do you evaluate light sources for circadian effect? The results
depend on the model you choose. (Example: Lucas et al 2015)
44. Do the researchers agree on the circadian response function?
Nope.
Dashed line here is a
Lighting Research Center
model.
“Measuring and using light in the melanopsin age“ by Lucas, Berson, Czeisler, Figueiro,
Lockley, Provencio, Skene, Brainard et al. Paper cautions that there is no accepted
model of circadian response, and it is highly context-dependent. No clear process for
applying this information. January 2014

How do you evaluate light sources for circadian effect? The results
depend on the model you choose. Example:
46. Example: Lighting for Neonatal unit
• Design to lux or circadian lux? What model?
• Design at multiple times of day?
• Measured at eye or workplane?
• Who gets control of lighting/programming?
• Design for the mom, baby, day nurse or night nurse?
• How does light spectrum affect tissue color evaluation?
(Cyanosis, jaundice, redness)
• How do you know if it’s working?
WE DON’T KNOW. NEED STUDY AND DISCUSSION.
47. • Change illuminance at the eye to get primary effect.
(High for day, low for night for diurnal humans)
• Change CCT to get secondary effect. (High for day, low
for night for diurnal humans)
Remember that individual needs for light vary, according to
age, health conditions, circadian cycle, light history, work
schedule/social schedule.
Light “treatment” may vary for different individuals using
the same space.
48. LRC model for scene
brightness spectral response
• Increased sensitivity to
short wavelengths
• Different from mesopic
response
• Seems to be a function of
photopic, scotopic, AND
ipRGC response.
• Varies according to
adaptation luminance
Besenecker, Bullough and Radetsky 2015
49. • Scene brightness may
contribute to perception of
safety
• Blue wavelengths will
increase scene brightness,
and perhaps allow reduction
of photopic illuminance
compared to HPS?
• This may be why LEDs
LOOK so much brighter than
HPS at equal light levels.

50. • What is a Lumen?
• Other Types of Lumens and Lumen Limitations
• Lumen Alternatives
51. A proposal by Dr. Mark Rea of the LRC:
• Define the “universal lumen” as the
area underneath all the photoreceptor
sensitivity functions
• Define the shoulders as the S-cone and
the L-cone curves (everything in grey is
included)
• Advantage: Doesn’t shortchange short
wavelengths for nighttime vision or
circadian response or brightness
response, for example.

52. • Disadvantage: Doesn’t characterize
any specific response accurately.

60. Visual Efficiency (Visible Radiant Power?)
“The quotient of the total radiant flux emitted w/in visible
spectrum by the total lamp power.”
Symbol = vis
Unit = radiant flux (watts)/input (elec.) watts
= (%)
65. • Leave the lumen alone. It’s a metric we all
know.
• Use the color data from the LM-79 sphere
report to sum the radiant power at every
wavelength in the visible range. (Visible
radiant power)
• Use a spreadsheet with different action
spectra to evaluate the SPD for the lumens
you need for your application (photopic,
mesopic, scotopic, melanopic, circadian, blue
light hazard, material damage, brightness,
whiteness, geranium flowering, and whatever
new photoreceptor or material response
comes along in the future…..)
vis = 0.32
66. • Additional way to analyze energy efficiency of a
light source for a specific application?
• Use the color data from the LM-79 sphere
report to get full visible radiant power. Multiply
by Vλ to get lumens and by alternate sensitivity
curve or action spectrum to get alternate lumen
count (e.g. mesopic lumens).
Specific application efficacy?:
Full visible radiant power X sensitivity curve or action spectrum
=
Electrical Watts
67. Conclusions
• The lumen is a metric that works in narrow conditions
• Alternate sensitivity curves or action spectra can be applied
to an SPD to determine an alternate type of “lumen.”
• CCT is a poor way to characterize an SPD, so use the full
spectral data.
• Alternate “lumens” or visible radiant power can be used in
addition to photopic lumens to evaluate performance of
white light
