    I bought this set to make a really bright spotlight: it has fulfilled my expectations! It is about as bright as a halogen 500W tube and the colour is nice (I bought the warm white version), it fits well to my other warm white lamps which means it should be around 2700-3000K. It needs good cooling! Only drawback: no data sheet on properties, how to mount it or other instructions. I even had to find out where to fix the input cables on the LED chip (of the two protruding side panels one is and the other -, there is a and - sign on the plastic board, but it does not show which of the produding side panels is which). Also it seems the cooling aluminium panel of the driver may not be used to mount the LED chip too - it needs a separate heatsink.

    I have bought 2 of this led chips, last week i did many tests on them and they are very good. You have to be careful with the fact that these become very hot, the best is you put them on a heatsink with cooling and don't cover it or keep it to close with walls,floors or anything that is flammable (same as other lamps above 100 watt). This lamp is really bright and just light up my garden at night. The light beam is very wide (think about 160° or something) Very much light for very low price. I'll think about uploading a picture at the garden.

    Blindingly bright, with the supplied driver I measured 66W input, but certainly bright enough for my purpose. LED module is likely good quality as all lit up at the same test input voltage.

    big heat sink needed the power supply works well. I use indoor and I am satisfied of the light more than the previous one (two 150 W halogen lamps)
