I am ready to buy another light for vegging and was hoping to get some opinions on what to buy. Can some of you that use t5's tell me about your experience with them? And why you think they are better than the metal halide. Thanks.
Most 400W MH lights emit 36,000 lumens or around 90 lumens per watt. If yours emits 40,000, you are getting a little more than normal. However, the T5s put out over 92 lumens per sq ft, so it is really quite close.jonath4n said:THG, how many watts of T5's are you running?
I make make the change back to t5's,
I'm running a 400w MH, but I also have access to the 4ft T5's 5k L.. My MH claims 40K Lumens, to match that with the H.O I'd be using more wattage?
Sorry stupid stoned and trying deep dive into thought lol.
I am a little confused about the size of your space...is it 5' long, 4' wide and 3' tall (dimensions are generally written l x w x h)? If height is a concern, T5s can give you a fair amount of extra space. Most of them are only 3" or so deep and the plants can be right up next to the tubes. I only get burned leaves if I actually let the leaves touch the tubes. I generally do not raise and lower my light--I raise and lower my plants.jonath4n said:My space is small, 5x4x3. but only using 3.5/5ft hi.
The heat reduction is nice, I just don't see the wattage reduction being great enough to swap EVERYTHING out lol.
Although its easy with these Yo-Yo hangers, I love them!
