maximum/acceptable grow tent size for 45x 1W LEDs
    #619667 - 04/22/12 08:15 AM (4 years, 7 months ago)

hi all,

been wondering if 3'x3'x5' (inner reflective surfaces) would be too big for a red/blue LED system made of 45x 1W pieces.

Thank you :smile:

Yea, that's probably way more space than you need for that little amount of light...

I see. What'd be an appropriate size? 2'x2'x5'?

I see, thank you. :smile:

It's that since they each emit a single wavelength, in this case the ones most absorbed by chlorophyll (red & blue), even a single watt of pure red light by LED would require a multiple watt lamp to irradiate the same 'red' quantity of light, because they also emit green, yellow, UV and IR light.

With only 45 watts at 1 watt per LED, I'd say 1 to 2 square foot at best.

Many thanks :happyweed:

I know 3w pieces would have had a deeper penetration than 1w ones, though I hear that based on current LED technology, they're less efficient watt-wise than 1w ones, like they emit less light than 3x 1w and more heat, though they cost less on a watt basis.
