    We received some Price Match with some ebay sellers who have better prices than us. What we say is that you would get what you pay for. In order to provide more options, we have add the different die sizes. The die is the chips encapsulated in the LEDs. In the past, SatisLED all sells power LED with 38mil Epistar dies which is proved the most stable dies in China LED industry. However, more and more people use China cheap dies to make the power LEDs and sell them at very low prices. And you can not tell the difference by the pictures. So now decide make gradings for them. And be sure to choose the die size before you add them to cart. Here is the difference between our difference size dies used:

    Advantage & Disadvantage

    32 Mil

    China AquaLite


    Cheap, LM/W is lower, Lumen Decay is large

    (Unless you care about the price a lot, not recommend)

    38 Mil

    Taiwan Epistar


    Price Proper, Stable Working & Low Lumen Decay

    (Regular stock of SatisLED and Highly Recommend)

    45 Mil

    Taiwan Epiled


    Lumen higher, Not as stable as Epistar Dies and higher decay

    (Price higher but performance almost equal to Epistar 38mil)
