DIY t5HO "hood"/reflector

Thinking about building a housing for a single T5HO bulb. What are some good ways I can create a housing and reflectors? Is aluminum tape good enough or are there better ones I can use. And regarding housing, I don't know what kinda of housing I can use. Maybe PVC pipe?
Any help appreciated Thanks

Hi pandamonium,

For what size tank? If it is 48" long I would do an AH Supply T5HO kit; they are easy to build with easy step by step instructions and have excellent reflectors. If you ask they will include instructions for a DIY enclosure.

My tank is a 40 breeder so 36'' long. I was thinking to use PVC pipe cut in half and lined with aluminum tape. I don't know if someone else had a better one or has done it before with good results That site looks good though. I saw a reflector for an 18W T5HO so maybe if I cannot find a way to DIY it.

Hi pandamonium,

If you would consider CFL here is a "gutter light" I put together last fall. I have also done a 2X36 watt AH Supply kit on my 30 gallon (36") which is great!

30 Gallon with AHS 2X36 watt CFL

That's a really nice looking tank and that gutter idea is really good! I am gonna look into that. You used reflectors from the AH Supply right? Do you know where they are based? I want to try to get everything locally but if they are local too that would be awesome. I'll look into your build and if I have questions I will post it here!

Hi pandamonium,

AH Supply is in Bloomfield, NY 14469. Yes, the kits contain everything needed (including the MIRO 4 reflector) except the the bulb and the enclosure. BTW, they have good prices on 36 watt straight pin 6700K cfl's which are difficult to find.

If you decide to make your own reflector, try to make one with thin sheet aluminum, like roof flashing. Shape it like \_/ with the bulb in the middle. Adjust the flaps on each side so you can see an image of the bulb on each side of the bulb. That will double the light from the bulb. AH Supply reflectors are better, increasing the light from the bulb by at least 2.7 to 1. I wouldn't use a aluminum foil lined section of pipe or anything else, because you couldn't then adjust the angles to get the most light.

Ok Hoppy that sounds good. You have commented on my other thread about lighting. I think I may go with the worklight or new 2 bulb T5HO fixture. According to your chart, the new T5HO fixture will have to be 12 inches above the tank to have medium light I believe. If I do not do that, then the worklights is the thing to do for me.
