1) The document compares traditional garden lights and solar garden lights, noting that solar lights do not require wiring, electricity bills, or risk of electric shock. 2) It states that the quality of a solar garden light matters most when making a purchase, as low quality lights may not work after rainy days or have batteries that only last 1-2 years. 3) The document describes EcoTawsun solar garden lights, which can store extra electricity to work for up to 7 consecutive rainy days through a brightness adjustment technique. It also allows users to change batteries themselves.

2. When purchasing a solar garden light, what do you care
most?
The Price?---Traditional garden light is cheaper.
The Shape?---Except for the solar panel, what’s the
difference of shape between a solar garden light anddifference of shape between a solar garden light and
a traditional one?
The quality ?---I’m so lucky that I found you.

3. What’s the difference between a traditional garden light and
a solar garden light?
And WHY?
First we need to think about the question below.
Comparison Traditional garden light Solar garden light
Labor Need people for laying wires No wiring thus no labor costLabor Need people for laying wires No wiring thus no labor cost
Electricity bill Yes No
Hidden threat Electric shock No e-shock since uses AC of
low voltage
When the power
off
Not work unless with a
generator
Not relevant, still work
… … …

4. Comparison Traditional garden light Solar garden light
Cost Light cost+ labor and wiring
cost+ electricity bills
Light cost only, but few months
later need a new light
When you bought a solar garden light of ordinary quality (without warranty)
Really?
It seems that a solar garden light is more economic, convenient and
safer than a traditional garden light.
Work Not work when power off May not work after one rainy
day; not stable, don’t work exact
hours/night
Battery No need for battery Batteries with only 1 or 2-year
lifespan, and can’t be changed
… … …
Not that real when the quality of a solar garden light is just ordinary.

5. ---A solar garden light without good quality won’t help you
save any money or avoid your trouble, and won’t even light
up after a rainy day.
So now we can answer the question:
Therefore, it is wise for us to put the quality first when
Why does the quality matter most when purchase a solar
garden light?
Next, what is a good-quality solar garden light?
Therefore, it is wise for us to put the quality first when
looking for a solar garden light.

6. Let’s just start from the concept “rainy day”
Have you ever noticed how
many rainy days usually
appears in a row at yourappears in a row at your
place?

Hey mom!
Can you see my hands?!
Rainy day is to solar light what power off is to traditional light

9. So “rainy day” is a big problem for solar garden light
Some of our peers claim to last for 3 continuing rainy days.
Many of them won’t tell you anything about rainy days.
If you don’t know this, there may be some problems after
a rainy day especially when the solar lights are used on
the fence of your company or park, a total disaster.
Now you may think, a solar garden light that can hold on
for 3 rainy days should be of good quality.
NO, you don’t know EcoTawsun with 7 rainy days yet.

10. We “steal” some electricity from the periods when the light doesn’t
need to be that bright. So that we can store more energy and hold on
for more continuing rainy days.
How can we do this?
How do you
“steal” electricity?
Do you know PWM? Kidding.
You don’t need to know PWM, just
know that we adopt this technique
to change the light brightness
E
to change the light brightness
according to human daily routine.

11. Light power/brightness changes with time going on
We have types with 12-
hour working time per
night and continuing 7
rainy days.
Also have types with 8-
hour working time per
night and continuing 3
rainy days, which is
brighter.
EcoTawsun is just beyond “good”

12. Besides, we take fully use of the
space, setting two solar panels in
the lampshade. Therefore more
sun light can be absorbed and
sent into batteries.

13. Another skill, you can also ask a question when buying a solar garden
light
How can I change the batteries?
You’ll get the answer
Sorry but you can’t change the batteries in a solar garden
light.
Why?
They can’t because they sealed the electronic stuff to do water-They can’t because they sealed the electronic stuff to do water-
proofing. Besides, what’s the point to change batteries when the light
should already die? That’s common in the current market.
BUT EcoTawsun has the delicate structure design, to let you
change the batteries by yourself, even provide you with the
whole small parts to play DIY. We are also eager to know how many
years can our lights last for in your hands.

14. A gift for electronics lover?
A toy to have fun with your
kids?
Does SKD reduce the tariff
in your country?
Is it more convenient for
you to purchase batteries
by yourself?
EcoTawsun has considered all of these for you.

15. EcoTawsun is exceeded in the market, from the
electronics design and structure design.
If you are also looking for something beyond “good”,
we are born for each other .
