As far as light output goes, I think they would be about the same. My experience is in general lighting characteristics so I can't tell you which would give you the best light, only that 2 150 MH lights put out about the same amount of light as 4 t-5's.

I have the same box and couldn't find any threaded fittings at the local hardware store, but I needed to use flex hose anyway so I just forced it over the threads and reduced it. I later learned that 1" PVC fits inside the fitting. The threads threw me off too. I saw on post that said they...

Yeah, the further along I get into this, the less the savings I'm seeing, but I still think I can get more bang for my buck. I plan on sealing the lights behind arcylic in the hood. One of the things I hate is the amount of light that's lost from the cheap plastic on my current lid. I plan to...

Thanks for the advise so far. I agree that doing it cheap won't be cheap if not done right. So, you don't need any lighting in the 6500 spectrum? Okay, I can scrap the CFL's, no savings anyway if I can't use standard bulbs. I'm still leaning towards the t-5's, though after calculating the...

Hello, all! I need some advice on lighting my 55 gallon tank. I want to add some LPS corals and don't have the lighting I need. I'm also poor so the cheaper the better :D. I'm leaning to wards T-5 lighting mainly because of cost. The biggest question I have is how much light do I need? In...

That's not exactly correct, but close enough. Let's say I'm trying to find the least expensive way to achieve the needed light levels. How do I know how many LED's I would need vs how many T-5 lamps. I can get the color spectrum I need simply by choosing the right bulb/led, but as far as how...

I like Lowe's :D

I agree with the others on the level of shock you recieved. Any saltwater on your and and the conductors of the plug would have provided an addition path for electricity to flow, so you most likely got a little leakage current as you were disconnecting the power. I once soaked a canister...

This is something that I have found very perplexing. Why is the lumen output not an important measure in selecting lighting? While I understand the importance of PAR and wavelength output, when it comes to intensity of the light everything still references power, i.e. watts/per gallon, watts...
