20W 30W 50W Full Spectrum COB LED Plant Grow Light DIY...
Very good, I made a mistake ordering 110V, but I put them in serie and run well.
These seem to run hot even with a large heatsink.
exelente
20W one is bright and you need a heatsink. I use a big CPU heatsink and it gets to around 40C. Soldering it is tricky. The aluminum backplate makes soldering difficult if your solder iron is not powerful enough as it draws a lot of heat.
soldering the connections requires a powerfull soldering iron and some practice. After that is done it works great after plugin it in. light spread without lens is very close to 180deg. requires a suitable cooling setup but worth the effort no other lamp is close as effective and cheap as it comes to light per money
MUY BUEN PRODUCTO GRACIAS
The 50W is like a tiny sun on my work bench. I expected it to get hot, but it only gets warm mounted to an actively cooled aluminum heatsink. It's light has a pinkish/purplish hue. Impressive value.
verry happy
Unfortunately I ordered 110V version, but need 220V, so cannot test it :-(
