View Full Version : how to wire new lights into old hood?

07/26/2008, 11:12 AM
i've got a 220watt hamilton pc hood that has been running for 8 years fine. i would like to at least double my wattage with more pc bulbs (and additional fan, of course). at best, i could replace with t5s!

basically, is it pretty strightforward simply splicing the wiring of the new bulbs in with the current bulb wiring? should i add an additional ballast? how do i add the fan into the wiring? I want to be able to use the current power switches that i have to control all the lighting and fans.

Any guidance would be most appreciated!

You would have to add another ballast to add more lights. I think it would be best if you got a retro kit, either T-5 or pc if that's what you want. The kit would come with a power cord that plugs into the wall, you could tie the hot into your existing switch along with a 120V fan as long as the switch is rated for your current draw. You might want to post pics, how much extra room do you have?

i would really like to keep my current hood, if possible. i have some space limitations and this hood fits perfectly. there is plenty of room to add 4 more 55watt pc lamps (currently, there is much more reflector than lamp showing).

i just worry about splicing in the hot wires to the existing wiring...as you mentioned, need to make sure that it can handle the load. what i need to know is do you simply splice in coordinating wires (red to red, black to black, etc.?). i do not wish to either electrocute myself or start a fire! i am not the handiest of people, so a lot of guidance in this area would be most beneficial!

if too much trouble, can examine a possible complete replacement with a t5 setup? but i do believe this will be way more money. my corals are doing fairly well under the current setup, not growing out of the tank, but growing nonetheless. i'm sure i would love a better spectrum of lighting, but if i can get by with more light, then that works for me.

you need another ballast to run more bulbs either way. cosider the T5 setup if expenses allow

thanks for that! yes, i believe i will invest in an icecap 660 ballast, just to cover all my bases.
still looking for some help on the wiring itself, if possible.

thanks for the help!
