So I recieved my powersun I ordered from amazon today, and turns out it was defective. Filament was twisted and burned a crack in the bulb. I have a backup bulb that reaches good temps but only provides UVA. I have a baby RT coming tomorrow, so my question is how long will a tortoise go without UVB light healthily? It should only be a day or two (Amazon Prime) but just wondering if those few days will affect it's health in any way.
