After sell service:We provide
free product after we confirmed that our products had quality
problems;but please don't open the lamps without our
permission. We make
driver by ourself(UL driver for **0W***0W led lamps)
We open modules for the casing
by ourselves.
Here we explain some details about led
chips:
Here I would like to introduce you
something about Bridgelux chips; Â As I told you
the chips have normally THREE kinds**-size of the chips; they are
*8mil, *5mil, *0mil. And *0mil is the best, and most expensive.
*8mil only for 1W using, *5mil and *0mil could work as 3W, which
means if we make a light to be *0W, we can use 3pcs chips to make
it. Some company sell lower price as I exampled.
 As you must
know P=VI, when we say how many
lumen for each watt, we means the led lumens. Led also has its
voltage, lower voltage means better chips. Normally they are
*8V**6V. Of course the
Iis normally **0mA. For example, during the led voltage is
*0V, the power Pwill be
*0*0.*5=*0.5W, during the led voltage is *2V, the power
Pwill be *2*0.*5=*1.2W. So the led
voltage affected the led power. Â Another Chips have some
levels, as bridgelux, it has D1 D2 E1
E2 F1 F2…..people use first four levels
mostly.
D*-lumen is about
****5LMÂ Â Â Â Â Â Â Â Â Â Â Â Â Â size
of the chips: ******5mw
D*-lumen is about *****5
LMÂ Â Â Â Â Â Â Â Â Â Â Â size of the chips: ******5
mw
E*-lumen is about ******5
LMÂ Â Â Â Â Â Â Â Â Â size
of the chips: ******0 mw
E*-lumen is about ******5
LMÂ Â Â Â Â Â Â Â Â Â Â size
of the chips: ******0 mw
F*-lumen is about ******5
LMÂ Â Â Â Â Â Â Â Â Â Â size
of the chips: ******0 mw
F*-lumen is about ******5
LMÂ Â Â Â Â Â Â Â Â Â Â size
of the chips: ******0 mw
NOTE: 1W=***0mw; as you all of you
must know led light has many heating, normally *0% for brightness,
*0% for heating. From the up details, you must know which level
chips are best, and how many percent for brightness and how many
percent for heating…right? For example, D1 chips, it has only
****7.5% for brightness; but F2 has ****8% for brightness.
See? Â So you must be
clearly that why so many companies have so many different prices,
of course you can choose it by yourself. The lumens we said were
only the led lumens. When we put on the glass and lens, the whole
product lumen will decreased, please know that. When you see the
test report of the light, that’s the total power of the light
included the driver power. Here you must ask how many for driver
power? Normally the driver efficiency is about ****0%, UL driver
*5%, which means **0W light, extra ****0W are from driver, 5W from
UL driver, wish you can understand what I mean? If not, please ask.
So from this way, you can calculate out the whole product lumens to
suggest all of your clients, you can also explain what I said to
them. Â Nowadays, more
and more people ask for better price, but they never know factories
give what kind of chips and led and driver, and housing. Different
quality housing will affect the whole product lumens and light
life. Lower level chips will give brightness losing during days
passed. That’s the reason why some sell lower, some sell
higher.
For
more details, please leave me messages, we will try to reply asap!
Thank you for your viewing of our product,have a nice day
:)
