T5 compare to LED lighting

[dota]

Okay, im still consider to buy the led or not... If my algae cant go thicker in 1 mnth time, i would change it to led

By the way, if 1 side using led 3w x 30 pc, n the other just T5 bout 72w.. Wat happen to the screen growth ? Will it be stronger..?

LED and fluorescent can't be compared watt-to-watt like that. 90W of LED would be at least twice if not 3x as powerful as 72W fluorescent. In other words, you would have a bare screen under that much LED light.

For LED, use the following formula:

for Regular lighting level, 1 3W 660nm Deep Red on each side of every 8 sq in of screen
for High Intensity lighting level, 1 3W 660nm Deep Red on each side of every 4 sq in of screen

hi Guys.. FINALLY, i just bought a DIY LED for my scrubber but only for 1 side ( i would like to see how it goes 1rst )

i have 3w x 36 pc (24pc 660nm Red + 12pc blue) actualy i ordered 3w x 30 pc.. (but he gave me extra 6 pc)

i have reduce the photoperiod from 18 hr to 15 hr / day, and also i moved the led back a bit ( bout 3" )

i hope this will bring thicker n greener alage

here are some of my LED pics for scrubber. Screen 20 " x 6 " ( with 3w x 36 pcs)

Do u guys think, any benifit of mixing with the blue..? at the first i want it ALL RED, but the seller suggest me to add some blue.

because if its better with all RED, i would change it to all RED

Very nice, since you already have the blue, see how it grows first

[dota]

oke, i just worry the power is not as stronger as all red

should i keep the light run 18 hr ?

[SantaMonica]

Seems a strong light, so start at 12 hours.

[dota]

its been a week, but the algae doesnt seem start growing more.. ( or does the algae adjusting with the new light source..?

[SantaMonica]

Light is probably too strong.

Ok, i will try to move it back a bit, and reduce it to 12 hours ? Or less
