How to add lights into a 4x2x2

[u/ihatemeanmen]

I just got a new 4x2x2 for my boy and it’s a solid wood enclosure with glass sliding doors on the front. My husband and I are discussing lighting/heating and we cannot seem to come to agreement on what we should do so i figure i should ask the experts. neither of us like the idea of having a fixture on the inside with a cage so our options are drilling a couple holes large enough for the emitter and the lamp and attaching mesh wire for the lamps to sit on (my idea) or cutting the entire top open attaching mesh wire to sit the lamps on top (his idea). His problem with my idea is he is scared the wood would catch on fire with having the lamps so close to it and my problem with his is it would let out so much moisture. what should we go with? or if anyone has their own idea we’d love to hear it

I made one with the cut outs and I really like it. So much I am making another one. My cut out is just a little bigger than the dome. I have had no problems with it and no burning or smells like it's burning. The problem I see with the full mesh top is holding in heat and humidity. There are post all over from people with mesh tops asking how to keep humidity and heat in because they are losing it. So you will cut it all out and have to buy something to put over it to hold in all of that which you had in the first place. He could use ac duct tape on the wood if he is that worried about it. I put rags against my domes to thaw my rats and never had those even singe.
