lighting descision

[blind1993]

i am trying to see what would work better for me, here are my 2 options:

i can get a pfo dual 175w retrofit for a decent price, i will have about 9 inches to work with in my canopy and can add fans if needed but my tank stays around 77 in the summer. i will have 2 10k bulbs over the tank and i know i will have enough par for anything i want but am worried about the heat and electric bill(dad)

or

i can get another 2 bulb t5ho retrofit and have a total of 4 bulbs with indivdual reflectors but i would need to save up more money, dont think it will look as nice as the MH.

btw the tank is a 55g with a canopy.

Go with the first option if it is indeed cheaper. I've seen people with dual 150 halides and make do without a chiller. The 175 will be pushing the heat issue but it should be manageable.
