You should be able to handle the install all by your lonesome Everything is color coded and goes together very easily. I have no electrical experience at all, and the whole project took about an hour and a half. All you need is a few drill bits, measuring tape, and a philips screwdriver. I believe that they will fit into most any standard hood, although you can measure your hood and compare it to the specs on ahsupply.com to make sure. If you have any other questions, let me know, I'll be glad to help any way I can.
Yes I got the combo bulb, half 10,000k and half actinic. Its a little blue but I like it. Brings out the fish colors better and the plants seem to look greener. I was very impressed with ahsupply's kit. One day soon (since i got the new job) I will be getting pressurized co2 first, then 4x55 watt kits from ahsupply for my 75. I think i'll go with the 6700k for that tank though.
