Hey guys,

Recently Purchased a couple of chinese 21 watt e27 light bulbs with Intention of popping out several of the white LEDs on them and replacing with 450nm royal blue leds and 420nm actinic leds.

I was planning on doing 3 warm white leds 3 royal blue 450nm leds and 1 actinic 420nm led per light bulb.


If anyone is interested I could sell one shipped for 6 bitcoins.

Will also do a different ratio of royal blues to whites.

If someone wants a bulb order of 5 or more I will knock off 20%...

Thanks,

Oh yeah, optics standard are 20 degrees so they are spot lights... I can change out for 60 degrees if you prefer.

Yup... The spectrum I was going for with these is more suitable for saltwater tanks... i.e. coral growth. But you may be able to use one of these for a planted fresh water aquarium... Usually I think you'd do 2 to 1, white to blue LEDs.
