New projector lights!

[Terra]

Hey all,

I got some projector lights off of eBay, and was wondering if you have any tips to keep them running for a long time? I've heard horror stories about moisture getting in and ruining everything.. is there something I could apply/spray on to keep this from happening?

Do you have any other general tips?

Thanks!
Ian
