Cool Reef lighting.

I am building a 58 gal reef. It mesures 36"-18"-24". I am putting in a retro fit halide system, and was wandering if I should do one or two bulbs. I am going to be useing 175watt ballasts and twenty k lights. Both are single ended and both are the same system. My question is two bulbs too much or not. I will not have reflectors just solid with color on in side of the canopy. Let me know your opinions thanks

175w 20k bulbs suck as far as PAR output and with no reflectors being used I would say you will need 2.

That's even less output than the 175w...so 2, but with a 24" deep tank you would have to watch where you place the corals.

There is no difference between HQI/DE (double ended bulbs) and SE (single ended) mogul base bulbs except for how they connect to the base. The brand of bulb matters way more than the style of bulb. There are no SE 150w bulbs and no DE 175w bulbs, but there are both DE and SE in 250w. The most powerful 250w bulbs, in term of PAR (measured in PPFD - Photosynthetic Photon Flux Density), is an Iwasaki 65K SE bulb at 189 PPFD, followed by an XM 10K SE bulb at 182 PPFD and 3rd is an EVC 10K DE at 179 PPFD. Some SE bulbs perform better than DE's and some DE's perform better than an SE.

Larry, you are just a fountain of information when it comes to lighting. Is this all coming from Vijay's research?
Isn't some of his research becoming a bit dated in that some manufacturers may have changed their bulb composition to increase PAR?
I've read his article comparing LEDs and so I bought the new PacSun units for my 125. They should be in next week

Cmor, all the #'s do come from Sanjay's Lighting site. What bulbs have changed? I try to keep up on the MH lighting and didn't see or hear of any manufacturer who changed their bulbs.

Those PacSuns look awesome, but they are WAY out of my price range. I don't know if I have $3,000 into my tank, let alone spend that on lights only.
Sanjay is also swapping out the 3x400w MH's over his 500g tank for LED's.
Here's his article for those who may not have read it.

Well they're not 3k, but they were over 2k. The PFO Solaris wa over 3k, but is no longer sold due to patent problems. I'm not sure how the new LED units are getting around that little problem. Possibly by NOT saying they are aquarium lights, but accent lighting or some such thing.
The PacSun units I am getting are made in Poland. I got them in a group buy on another forum for a pre-intro price.

You can see them at Pacific Sun Black Python BT EX 120W - MASTER - €760.00 : AquariumLed.eu!, Powerfull light for you reef aquarium!
