If you rest your double lamp directly on that top and it is touching that plastic cross member it may get melted some.
The good thing about the stand is you will be able to hover your lamp over the screen without touching the plastic.
Here's a tip if you don't want to be spending money on bulbs every 1-3 months:
Buy a 100 or 150 watt bulb and hook it up to dimmer. Use a temp gun to dial in the proper heat 88-90. Went done right your dimmer will be turned down to roughly 50-60% power.
This keeps your bulb filiament from getting too hot and burning out.
I have done this for over 2 years on 4 tanks and have yet to replace a bulb. And these bulbs run 24/7.
