I have this plan to make a battery powered moonlight/noturnal light for my jungle enclosure, to use for an hour or two on feeding nights. As its only a 2ft glass, mesh top setup i didn't want the expense of another reflector to run a moonlight bulb and I don't want it to effect the temp gradient. So I have come up with this, I'm going to use a small LED torch like this one Handheld Work LED Light Torch w/ Hanger Magnet | eBay and simply taping a piece of frosted dark blue or purple plastic over it. Do you think this will work?
