efficiency
HPS and MH
- Second most efficient and are
- Currently being used to replace MV lamps -
Standard for traditional new installations and
replacements
- Poor CRI
LPS
- Most efficient
- Very poor color rendering

Typically mercury vapor lamps are used for street lighting and
other outdoor lighting (car parks, etc)
Lamps are bring replaced with energy efficient lamp High
Intensity Discharge (HID) as follows:
- For Street Lighting
High Pressure Sodium - 200 to 400 W (Orange-White color Light)
- For Warehouses, Outdoor & Parking Lots
Metal Halides - 100 to 250 W (Natural White color Light)
- Some cities (e.g. San Jose, CA) use
For Street Lights
- Low Pressure Sodium - 180 W (Yellow Light)

45. EkoLum Segment Gateway simplifies Installation
Main challenge
- Installation needs to be done by electricians with no LonWorks
skills
- Many devices of the same type (e.g. lamps) need to be installed
on the correct location
- Changing damaged devices needs to be simple - System
functionality and reliability needs to be checked easily and fast
Installation time is money!
