how many watts is each of your tubes? I see they can come into many different wattage for that length...WeedHopper said:I have. I used a 4ft 6 tube T5 setup with 3000K bulbs for Flower. 6500K for Vegg.
This plant was under those T5s @ about 6 weeks flower.
that's a very nice plant for what you are running..WeedHopper said:54 Watts @ 5000 Lumens
Actually a 4 bulb, 2 foot T5 uses 96 watts, and emits 8000 lumens.Hushpuppy said:Typically the 4' T5s put out about 5000lumens and pull 54watts the 2' t5s are basically half that. If yer real space tight HTGsupply.com here in the States has a 2' 4bulb fixture that puts out 20,000lumens at 220watts total. Or yu can get individual bulb fixtures from accessdiscounts.com for $23 ea. and place as many as yu need and link as many as 8 together. And they produce very little heat in comparison to the HIDs or CFLs
Unless one is going to be used as side lighting there is no way to augment with the other type as both will need to be as close as possible for best results.pawpaw said:I'm going to augment my LED panels with HO T5s. Is any one here flowering with T5s and what (pseudo) color temp are you using.
thanks

:yeahthat:WeedHopper said:You get a much better Lums to Watt with T5's. Not sure ya need LEDs,,I would use more T5s..
In truth the main reason I'm using the LEDs is that I already have them. But It is not fair to compare LEDs to other sources directly in terms of lumen values without comparing how the spectra of the lights' plot against the PARWeedHopper said:You get a much better Lums to Watt with T5's.

Growdude said:cool layout, just be sure to use the reflectors from the T5, without them they lose lummens.
If they are T5s, they are 5/8" in diameter--the number after the T denotes the diameter of the tube in 1/8"pawpaw said:I'm using the Sun-Blaster single bulb units. They are verylightweight and under an inch wide. The housing is highlyreflective aluminum. At the least I will paint the back-panel brightwhite. I'm going to do some experiments with applying some dualmetalized Mylar film with spray adhesive. If that tests out wellI'll do that.
And thanks, any other thoughts, suggestions?
Doesn't mean squat if it's severely underlit, though!pawpaw said:In truth the main reason I'm using the LEDs is that I already have them. But It is not fair to compare LEDs to other sources directly in terms of lumen values without comparing how the spectra of the lights' plot against the PAR

Just as lumens don't mean squat if they are in the wrong part of the spectrum.Roddy said:Doesn't mean squat if it's severely underlit, though!
