Will 2x150w mh plus 4x65w pc be ok for a 90 gal?

I have a 60"L x 24"H x 18"D acrylic aquarium. I am debating on what type of lighting I am going to use to go full reef for this tank. Was thinking of going with maybe (3) 250W HQI lamps spaced evenly over the aquarium. Any thoughts on if this will be enough light to reach close to the bottom of the tank? Any suggestions on color for the lamp themselves? 15k, 20k, mix of some different ones?

Sounds like a good wattage of lamps and you should get decent penetration at 24" deep with 250 HQIs....what kind of reflectors are you thinking about getting? Any idea if you want T5 or VHO actinic supplementation?

hey guys, i currently am running a 36" Tek T5 6 bulb over my tank. it's a 36 long but a bit taller.
anyways, the reflectors ere getting a bit worn and i was thinking instead of replacing them just switch over to MH. i like the aquamedic hqi 250w. would this be enough for my tank. i have some sps, lps, gbta, and a clam on the sand bed.

MH bulb/ballast combo questions
MH bulb/ballast combo questions
I have a 250w MH hood/ballast, but the ballast isn't pushing 250w. It's stamped to run at a power factor greater than .98, but my kill-a-watt meter reads it at a power factor of .67, and it pulls around 170w. I ran it for one week and these values never fluctuated. I was told that under-powering the bulb was going to cause spectrum issues and shorten the lifespan, and I had another 250w MH I am using instead. I was wondering if it would be safe to run a 150w bulb in the 250w fixture with the 250w ballast that is only pushing 170w (around what I would expect a 150w to pull) at a PF of .67?
Also, I think this is an HQI (double ended bulb which looks like it just slides into the end's). The ballast has a cable like a computer power cord (three flat prongs), with the ballast connector being a recessed male. If I were looking for a replacement ballast for it, what 'style'/'form factor' would that be called (what should I be looking for when I shop for a replacement)? If needed I could take some pics of it...

Alright guys. Im about to setup a standard 75 gallon tank. I was looking at a 6 bulb tek light t5 fixture. But then one of the guys at my lfs is trying to sell me a 2x150 watt sunpod fixture. I dont remember which one, but I know it had a bunch of led supplements. I love LPS, but Im starting to get into clams. But if I had correct lighting, I imagine Id get at least some SPS.
So would a 2x150 watt hqi be enough for a 21" tall tank?

Anyone use the 14k 250W SE icecap bulbs? They seem like a good bulb for the price.
