Which is better?

[russianspy]

Should I....
(1)
2x95w VHO's
1x175x MH
Total watts: 365
(2)
4x95w VHO's?
Total watts: 380
I was thinking if i use a MH instead of all VHO's I would be able to actually have more coral choices...Maybe?

I'd go with the first choice. Is there any way you can get a 150 watt DE or 250 watt mogul instead of the 175 watt? Either of those bulbs would be better than the 175 IMO.

id go with option 1 also, but I would be lury on going to a bigger bulb. Heat and light will be getting up there esp on a 45gal. but thats just my opinion.

Whats wrong with a 175 MH?
I don't know what a mugol is!

The difference between a mogul and a double-ended bulb is that a double ended bulb puts out more light energy watt for watt.
70w DE = 150/175 mogul
150w DE = 250w mogul
250w DE = 400w mogul
A mogul bulb has the screw in type socket, and a DE has two ends that contact the sockets on both ends.

Well, I don't know

I say go with option 1 but try to get a 250 watt de they run cooler then the mogul base ones. Also what is the length of your tank and depth.

 

[russianspy]

My Length is 36" and depth is 24"

 

[flatzboy]

With that length and depth you should realy go with or you probably have big shadows on each side. I would with maybe 2x150 watt hqi because there more intense for your deep tank.

So whats the catch? My mama always told me you don't get something for nothing
I did some checking and they really dont cost much more and if your numbers are correct thats a huge difference in energy consuption. Do the bulbs burnout quick? produce massive amounts of heat?
