Otimo produto!!! qualidade me surpreendeu!!!
Very good product, very good light from a small led.
Led 30 Watt COB Used to make a greenhouse I use them with a power of 3 watts, which avoids thermal disspiation. To limit the current to 100 mA (under 30V), I use Microship's CL6 circuit. The result is very convincing.
I got the 30 Watts version running on 20 Watts in order to extent it's life and reduce heat. Mounted it to a 300 x 69 x 36 aluminium heatsink with some cooling paste in the hopes it is enough for passive cooling. So far, it seems to work. Heatsink is warm to the touch, not too hot.
Haci came the product my good
ok.they are gut
I like this DIY LED full spectrum 30W DC chips. Great for my projects. Put on a big heatsink and it will show its diamonds.
Great LED multigrowchips. Give them a good cooling and it will show its diamonds !
All arrived intact. Well packaged.
Very nice
