DIY LED Light.

2700Kelvin is the colour temperature of the light.

IMO, for planted, should get those with high Lumens... some LED does indicate Lumens...

By the way, the whitelight LED should not be 2700K... the warmlight LED is.
I got both LEDs... the website is wrong... must be lazy IT staff did not input data correctly.... very common...
