Hey grim
You sugestet Ge 6500K for my combinetion
Wath is the difrent between Ge 6500k and ATI 6500k
Thank you

The Pro Sun ATI lamp is nice but there arent too many left around. If you can get one they are great.
 
Hey Grim,

What, if any is the diffrence between T-5 HO and T-5 VHO? and does it change the life span of the bulb and the ballest?

Grim...am I never to see your tank with your current bulb configuration?? :( I may want to make a couple of bulb changes and would love to see the bulbs that you are running...pretty please????

Maybe I wasn't clear in my last response... My camera wont take an accurate picture of the tank color unless it is a closeup shot. For some reason anything beyond a moderate close up looks completely blue so I havent bothered to take a full tank shot. If I back out any farther than the one pic I posted (link below) it just makes everything look blue, like just having actinic on. The closup pictures will give you the basic look of the lights.

The shots I posted for you on the last page are the best I have. Closeups seem to look close to the actual color. As I pull away from the tank everything washes out blue with the camera I have so I don't even bother.

Just ordered a pair of Tek T5 reflectors and 24W ATI Blue+ bulbs. I will power these with an icecap 660.

They will be used to suppliment a single 250W Ushio 10k.

Unfortunately they will be 8" above the water over a 20" tall tank.

Do you think these will be enough to give more flourescence/pop my corals?

They should still help.

Hey Grim,

The T5 VHO is an overdriven T5 HO. As far as I know there is no industry spec for T5 VHO. UVL designed their HO lamp to stand up to being overdriven by an Ice Cap ballast and that is what they call the VHO lamp.
 
Oh Grim... I am really sorry to have been a pain... for some reason I never got your responses and I check all the time...dumb me!!!!! Sorry!

so does this mean that the UVL's will last longer?

Maybe, maybe not. If you overdrive your lamps it seems like they would because of the double coil electrodes.

No worries:)
 
are the 48" 54w retrokits from hellolights.com any good? i will be puting them on a 90g aga rr that will be mainley sps dominated but a few lps in the darker spots! please let me know!
 
Hey grim,
Sorry if this has been asked but I've been looking for so long now I don't know where I am! I have 75G mixed reef mainly LPS and Softies, but a few SPS up high. Color in the SPS is dark. I want to go from my current setup of 4 VHO URIs 2 Whites 2 Blues on an IC660 without reflectors to t-5 with individual reflectors IC or comparable. Would this be sufficient if I wanted to continue with my current SPS and maybe add a few more? Also I think the look is too yellow now, any suggestions on getting it to the 15-20K look? Thanks you've been a big help here and with you red house!

The lamp selection isnt great at Hellolights. I'd do reefgeeks and spend the extra 2 bux a reflector to upgrade to the Ice Cap reflector.

4 lamps will be plenty for sps up on the rocks. For lamp try

Front
ATI Blue Plus
UVL Super Actinic
UVL Aquasun
ATI Blue Plus
 
I wanted to know what the best reflector distance from the T5 bulb was (for those that separately mount the reflectors and don't use the clips). I do have the clips and was considering putting them on to guage the distance and adjust the reflectors, but wanted to be sure that would be optimal (IE: or that the clips merely put the reflectors off as far as their design would allow and still hold the reflector upright, but not far enough to be truly "optimal").

also, I have read about T5s being enough for sPS up on rocks, etc. Most of them have the lamps 4" off of the water (more or less) and the corals up to 18" - 20" down from the waterline. Would it be fair to say that 22" - 24" from the bulbs is as far down as an SPS can go and still receive enough light to sustain it ? Taking into account that the bulbs were run off of an IC ballast, using IC an IC SLR and were 80 W ATI AquaBlue Plus bulbs. Or am I really off base with my numbers ?

I also wanted to clarify that the best color/par bulb for stand alone running is still the ATI AquaBlue Plus bulb ? Or is there another with a crisp white/blue color and good PAR ? Would it be better to run two 3' bulbs end to end than the one 5' bulb ? (I don't need the extra 1' linear coverage, but am looking for more penetration.)

I am trying to use T5s to supplement our MHs, but not for color, more for filling in dark areas and lighting the front side of several colonies that are towards the front of our tank.

Thanks in advance for time spent answering my questions (and likely setting me straight on a thing or two :))
 
If you are going for PAR only the Aquablue is a good choice. Using the clip to measure the distance from the lamp to the reflector would be good cause I aint gotta clue about that.

If you are overdriving 80 watt lamps I would say most SPS would be good 16" (12" of water 4" of air)down for sure and montis a bit lower.
