Questions & Answers

Can I use this along with a food that contains vitamin D3?

Answer by Donovan • Aug 20, 2026
If you are talking about calcium power that you dip insects in then yes. BUT you have to be careful when feeding your reptile D3 since it can overdose on the vitamin. I feed my Leopard gecko D3 Repti-calcium 1-2 times per week. I feed him the same calcium without D3 5 times per week and I feed him vitamin A repti-vite once per week. Its pretty complicated but thats how it is owning a reptile. I hope this helped!

Is this no flicker ?

Answer by Chewy • Aug 22, 2025
This bulb is fast start and flicker-free.

I'm attaching a photo. The size of the box this little 12" T5 bulb came in is a ridiculous waste. Not only did the bulb roll around the whole way here, but now I have to get rid of this huge box. A padded envelope would have worked just fine. If this ever happens again, I'll not order from Chewy again. Plus, I only received one bulb!

This brand is great

I tested with solar meter and it puts out the exact UVB it says it will. I test every three months (cause I’m extra) it lasts

Arcadia Reptile UVB lamp

Rl The order arrived in good condition, both lamps arrived well but one of them almost started a fire, I think it came defective.

Arrived in one piece

I ordered this for my ball python. I recieved it without damage. The bulb was not broken, and I assembled it without issue. I currently have it piggy backing off

I ordered this for my ball python. I recieved it without damage. The bulb was not broken, and I assembled it without issue. I currently have it piggy backing off of my bearded dragons uvb because it's on a timer. Which means I have less things taking up plugs on my power strip.

Short lived

These bulbs burn out really fast. Had some burn out in 3weeks and some in 3 months. Very frustrating!
