The continuing story of crappy high power LEDs.

Yet another crappy high power LED from a shady eBay seller finds its way into one of my bench lights. This time it's the turn of what I can only describe as a fake 50W LED that walks the walk, but most certainly doesn't talk the talk. It does have the correct appearance of a 50W LED, but the 50 LED chips arranged in the traditional five rows of ten appear to be very small. Probably the smallest LED chips I've seen in one of these LED arrays, and suspiciously small enough to make me think they may be common chips used in 5mm LEDs. The backplate of the LED is also unusually thin and the weight of the entire LED module is around a THIRD of a typical high power LED. It just feels light and flimsy. The connection plates are unusually rotated at 90 degrees to normal, but the base does align with the standard mounting holes. The output is a bit "grey" in that it has a blue bias and is visibly dimmer than the LED in the other fixture. (A dodgy 100W one with leaky chips that is being run at 20W.) I think I may be changing this LED soon.... Even if just to get the intensity back up and a better shade of white.
