This is one of the 8W 24VDC IP65 COB led downlights, single colour (white) 4000k that I purchased, again direct from Chinese manufacturer to save $$$
Just a heads-up for anyone purchasing LED bulbs, if you want a globe rated for say 8W, make sure it is a single colour LED chip to get the full rated wattage.
If you get a multi colour adjustable (RGB) or (cool/white/warm) globe you won't get the full 8W output...much less.




This particular light globe will run direct from a 24VDC battery without an LED driver.
I have incuded a driver in the circuit leading to these globes to reduce heat output on the globe itself and to have a dimming function.
When cranked to full brightness, the heat dissipation fins are barely warm thanks to the PWM drivers.
A small current draw for such a high Lumen...surprisingly bright.
My preference is for natural white, so am sticking to the 4000K to 4500K colour range which makes life difficult when sourcing DC LED globes.
