2PCS LED COB Chip 50W 110V White Light Engine Integrated Smart IC Driver Free Solder for LED Floodlight Ceiling Light etc

Replaced some blown LED modules in two of the flood lights at work. Super bright, fully sealed, comes mounted on an aluminum backing plate, and was a direct fit.Some notes:1. Use thermal paste or epoxy to ensure it cools properly.2. You do not need to solder leads on to the unit to connect it to power (see next line).3. It draws less that 1/2 amp, so you can use solid core 18 gauge wire to connect this up to power. the wire easily slips right into the connector on the board (the "L" and "N", for load and neutral).4. It is not fully sealed and is probably not water resistant.

These are very convenient not needing a seperate driver.They do need a big heat sink. I add a 12 volt cooling fan at 9 volts to be quiet behind a 2 " x 2" finned heat sink.I add an aspheric lens at the chip and a freznel lens at it's focal length to make spot lights with very sharp edges on the pattern. Do use a grounded plug and wire with ground connection to the heat sink.The jacks for the 110 volts is a problem. Just pry the top off the jack and solder to the contacts.You will have to drill and tap the heatsink to attach the chip.I have not tried thin metal reflector / heatsinks.

Both failed within 1 month period

These are bright for sure, but they are not 50 watts. But considering the price they are a decent deal. The connection for the AC input is a little weak for my taste. They are supposed to clamp the wires in place but the wires can slip out on their own... and if there’s any shaking or vibration they will definitely come out, and they are 110 AC.. so that would be very bad. I’m sure I’ll figure out a way to secure them better. The clamp issue may not be in every LED but still it’s a significant issue. They don’t seem to get as hot as my other (verified) 50W LEDs but a heat sink should be used.

Works as advertised, simple and well made design. Only complaint is the hot/neutral solder pads are a little small

Comparable fit to a existing outdoor lamp that had a failure on the driver assembly itself. Although the output says 50w equivalent, it is not as bright as the light assembly it replaced. The output is still well worth the price, as it is still working, the original failed after 6 months. I would buy again at same price level.

Great product easy to use.

Cheap, fails too quickly, connections questionable.
