    This led is very bright. I suggest do not look directly to it, it can damage your eyes. Measured power was little over 150W. A good heat sink is must ! Do not operate without one. Solder the wires before you mount it in heatsink. It will be difficult afterwards. This is a quality product.

    These are great, put out a lot of light. no need to buy separate power supply. At our 60 cycle power here in US I could not discern any flicker. I will attach heat sink to back of panels.

    This is the brightest heater I have ever seen. The GOOD: does not need a driver, just connect to the power line and it works. The BAD: it generate a lot of heat and the heat spreader is Aluminium 160x103 mm only 1.5 mm thick. Needs a big heat sink, without it will burn in just a minute of work.The UGLY: It has 8 holes on the edges for the mounting screws, but the heat is generated in the center. So when it works and the screws are tight the Thermal Expansion of the heat spreader creates an air pockets between the heat spreader and the heat sink. Graphite thermal paste may help - I am working on it. Thanks Banggood.

    extremely bright led. can be dimmed with a variac. nasty to solder, made a alternative connection, by scratching off some copper. color temperature , spectrum and equality ledchips are very good. Did I tell this unit is bright? That is an understatement, what a fotongun!! Blinded by the light!!

    It is important to put a good heat sink so that it does not burn.
