Zoo Med 26042 Reptisun 15W 5.0 T5-Ho Uvb Fluorescent Daylight White Lamp, 12

Works great for my chameleon, these are better than the round lights in order for them to soak up enough uvb, also better to diagonally set it on top of the tank for better absorption

Arrived broken

Nice UBV light output. Usually use the round bulbs but wanted something a little bigger.

Plugged it in for my 6 months change and doesnt work straight out of the box

Fits well into the lamp I bought, and provides ample heat

These bulbs are great And I would highly recommend them

Horrible quality from merchant—definitely not true ZooMed quality. But DID NOT last ONE month. Last one that I purchased from a local store lasted over a year, and I only replaced it because they are not excreting light properly after one year.

Perfect! We use these for our bearded dragon and she seems to like it. She loves basking underneath it :)

These bulbs are very good, but until amazon figures out that shipping light bulbs in envelopes is idiotic theres no point in buying them here. Update: Amazons customer service assured me the replacement bulb would be sent in a box. Nope, another bulb in an envelope, although the second one did survive the trip.

Bulb never worked. As soon as I put it in the fixture, it flickered and then heated up on one end of the bulb to the point of smoking. Unfortunately, I waited too long to return.
