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;   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.   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 ****5LM              size of the chips: ******5mw D*-lumen is about *****5 LM            size of the chips: ******5 mw E*-lumen is about ******5 LM          size of the chips: ******0 mw E*-lumen is about ******5LM           size of the chips: ******0 mw F*-lumen is about ******5LM           size of the chips: ******0 mw F*-lumen is about ******5LM           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?   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.   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 :)
