so i have 2 set ups side by side, and for some reason both basking bulbs went out this morning. 2 different timers. so i need to buy basking bulbs TONIGHT !! what should i buy !? both tanks are 40g breeders so you know the dimensions already. was using zoomed 100w repute basking spot lamp. I've gone threw 3-4 in the past year so i hate this brand.
