Not necessarily cheaper, but a cooler, more even light distribution. The down side is that the light looks flat and unnatural IMO. My last tank was a 72G bowfront with 336W of T5 HO lighting, and I had plenty of light for SPS all the way to the bottom. That same tank would have needed 2- 250W MHs if I went that way, and I don't think I would have had the same light penetration from what I've seen of halides (I now run 400W MH)

I'm sure we've all said something like this at some point, and it's a good lesson for someone starting out. We buy something to get us started, only to to have to "upgrade" in the future to be able to get the results we want. Better to buy the good stuff first and save yourself a lot of money.

You might as well know now, this hobby is expensive!

Has anyone used the "new" Glo t5ho from Hagen. Not sure if the unit has individual reflectors or not. Not sure on the pricing either. Any comments would be appreciated.

The Tek light looks pretty sweet!!

Thanks for all the links guys. I've been reading bits and pieces of the RC one,
thanks Mark.

Well said Reefer Rob.

I really like my T5 and think it is a great unit (cost/looks/function), but after seeing Danny Zubot's tank, MH really does look spectacular. T5 gives you lots of options in terms of light combination, but w/o the shimmer its just not the same. However, that said, higher elec cost & heat issues are the price you pay!

I got a set of t-5s, The price is unbeatable . New waves from sunlight supply pretty much are the same as the teklights but much cheaper,(they dont have the nice black shell). I think they go for like 130 for a 4 bulb setup at golds (without bulbs). So around 230 for a whole 24 inch t-5 fixture with bulbs isn't bad. The price is a bit higher than a power compact, but I'm sure most people rather fork up the additional 50 to 100 bucks for t-5s. I personally haven't fired mine up yet but I'm sure the results are promising from what I have heard and seen.

Well, let's take a common 48" long tank. A reefer would decide to light this with either 2x250W MH or a 6x54W T5HO setup. Therefore you've got 500w of MH versus 324 watts of T5 saving you 176 watts per day assuming you had both on for the same amount of time. Over the course of a year that's over 27,000 watts of savings.

Assuming that you changed out your bulbs on a yearly basis, you'd still save with T5HO. Good name-brand MH 250W MH bulbs retail for ~$100/bulb. That's $200/year in MH bulbs. 54w T5HO bulbs run about $25/bulb x6 = $150/year in T5 bulbs.

Running an 8-bulb T5 unit would bring the electricity costs closer (432w vs. 500w) and the bulb replacement cost would pretty much be a wash.

The bonus with a T5 setup is that you'd be able to fine tune your colour temp more precisely using multiple bulbs instead of just one and you would need to add additional lighting to MH to get a dawn/dusk effect whereas that is built into any good T5HO unit.

As for which T5HO unit - I'd get one of the high-end Aquactinics units for maximum output given: 1) active cooling, 2) Icecap SLR reflectors, 3) Icecap 606 ballast (which overdrives the bulbs slightly - costing you a bit more )

[Reefer Rob]

If the Aquactinics come with come with an Icecap 660 ballast they would definitely be a good choice. Not sure what's in the Tek lights, may only be a Workhorse ballast, which won't come close to a 660. Still, if I remember correctly, the Powermodule has the most PAR of any T5 fixture. You did say you wanted to keep SPS

I picked up a couple of the GLO T5 ballasts used and have no complaints. Then again I have nothing to compare them too plus only using one of them to supplement MH and do dusk/dawn with actinics. The water proof end-caps are nice and hardwired back to the ballast. Have reflectors but weren't part of the GLO but still considering either the TEK2 or Icecap SLR as a little narrower than the one I'm using now (would allow me to add another bank of T5s in my hood). Reflectors though really don't seem an issue as if going the retro route, they just snap directly onto the bulbs and not that bad for price.

I bought the glow for my fresh water tank and it is pretty sweet, I would never have the ilusion it or any other T5ho would be able to replace MH (especialy after doing some PAR comparasons) but on a shallower tank like you are using it would work well. I would think that with your tank width two of the fixtures would be pretty good, and I would go for the 36" ones if you are planning on going to a 33 later.

From what I could find, Aquactinic TX5 are workhorse ballasts, and the Solar Flare models have IceCap ballasts.

Seems to be a lot of happy ppl with these lights on RC as well.
