Nagulagu Driver Free 50W LED COB Chip lamp Light Cold White 110V AC

I have 3 floodlights they have great housings but the LED chips are junk. This cob was the answer for me. A few minutes to remove the old chip rewire the fixture for 120v and install this chip using artic silver 2 part conductive paste. Worked perfectly.

Item arrived in anti static bag, wrapped in bubble wrap and in a small box. I used this COB chip to switch over a work lamp from those super hot 500W halogen bulbs to this. I have a super bright led work light now using only 50W now. Lamp still gets hot but a lot better than the old style. Gave 4 stars only due to longevity is unknown.

I used eight in my test project for a 4th of July fireworks display. These lights are very bright, one would light up the backyard. Each light was connected to its own channel on a Light-O-Rama CTB16PC unite. They dance to the sound of a recorded fireworks. The lights would flash on and off with the sound of explosions in the fireworks soundtrack. I mounted each on an scrap aluminum plates then on PCV pipes then attached to a second story balcony.. They were about 25 feet off the ground. We could not look directly at the lights, very bright, but I'm sure people many miles a way could see them. The show is about 12 minutes long and I ran it 5 times. So these lights flashed on and off for an hour.

Easier to solder AC power leads than expected. Blinking Strong Light. Dimmed from 0 to full brightness with Variac (still to try normal wall dimmer). No noticeable flicker at any brightness even when recorded by camera. Of course, must be mounted on proper heatsink with heatsink compound for duration usage. Nice Smart IC for custom DIY tech projects.

does just what I needed it to do, be an all season light in my garage without the cold start problem of fluorescent lights, with the added bonus that I can now see.As with many driver-less LEDs, there is a flicker that is noticeable.This takes a serious heat sink to operate properly.

I use some 100 watt led flood lights in the barn and even though they list 10,000 hours life it seems like they don't last very long and then quit. I took one apart, removed the single led panel and installed these two in its place. So far they have given me great service. I plan to order again and rebuild another one that has quit.

here is the test pic of my setup. Works perfectly and lights up a whole room 10 x 14 with no problem. Using a heat sink that I thought initially would be too small but no problem so far. Has been tested left on for 24hr straight with no issues at all. Testing now for 2 months with no problems. Definitely going to buy more.

This is a really bright led module. No driver required! I installed 4 of them on a 1/2" thick plate of aluminum. Then added a heatsink and fan to the plate. The current draw is about 63 watts per module. I would buy again.
