How does a cfl T5 high output match up to hps or mh?
54 watts times 10 = 540 watts would it be slighlty equal to a 400 or 600 watt hps or is that many cfls overkill?
i tried searching but did really find a thread dedicated to it

Well, from what i've read, T5's can be placed closer to the plants, which allows them to absorb more lumens.

For vegging, you'll have great results with the T5's. But once your plants get some more size on them, when you start flowering your going to wish the light from those t5's would penetrate into the plant further. A SCROG is the only way i'd use those through a whole grow. So i'm saying T5 for vegg would be better than a HPS (of same wattage), but for flowering the HPS will win out because of its lower light color spectrum, and the more intense light output which penetrates better, and puts out denser buds. Good luck

Years back my team and I experimented with running the high out put T5's as a HID replacement. We found the lumen didn't penetrate so the plants (as expected) and need to be kept small. Also, the T5 high output system put out a decent amount of heat. A 400 watt in the same space with the same air treatment produced far greater results for about the same energy consumption.

I keep T5's where they belong...in the veg room.

They are great but they have their place in the room. Those 4 ft fixtures are going to create heat. Most people use the CFL's because they DO NOT gen heat. The new high outputs still do so in the end your fighting the same battle you would with a HID with lesser yield. a small HID at 19 cents a watt won't cause a huge increase in usage. The tight buds will be worth every penny

Those are good CFL lights you have selected though.
