Lighting a Hangar Deck

And so, you have 5 layers, and 6mm space to stuff them in. Anyway, there are some combinations:

1) Hangar Roof, Frosted Acetate, SMT LEDs on PCB and Carrier Deck.
2) Hangar Roof, Frosted Acetate, Cut-out EL sheet, SMT LEDs on PCB and Carrier Deck.
3) Hangar Roof, Cut-out EL Sheet and Carrier Deck.

Its costly and so, you would need to try out the
EL sheets first. Just slap it on and see how bright
it is. Some inverters allows you to adjust the EL's
brightness but near in mind, they lose their
brightness over time.
