    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.

    Great 50W LED DC chips for planting. Blue and red spectrum for green plants growing. Very powerful and the plants are growing well under this light. Works fine low heat production but you have to put it on the aluminium heatsink to work fine. I like that COB chips, easy to mount and easy to operate with the aproprietary DC constant current driver.

    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.

    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.

    All 12 LEDs that I bought worked as advertised. Packing was poor- but these are sturdy items, so it didn't matter.
