Just a thought. I was working in my garage last night and I came across a couple of those halogen work lamps. I know that these cannot be used as DT lighting , however the housing, lense and reflector all looked very useable ? I bought these for $15.00 Canadian. I am wondering if anyone has ever attempted to retrofit these as MH chassis ? Additionally they are all labelled suitable for outdoor use so I would assume they could withstand aquarium installation...?
