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

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.

I previously wrote that when the product arrived it did not work. Because it was a light bulb and was packaged in only an envelope, I was sure it had been damaged in transit. HOWEVER, the bulb DOES WORK. I did try it three times, but apparently it was operator error...my husband was finally able to get it adjusted properly and it does work. I apologize for my previous review, but I did, in fact, try several times to get it to work. I would recommend, perhaps, some better packaging, just to ensure no in-transit damage is done. Thank you.

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.

Came fast, came in one piece, and works! My turtle thanks you!

These bulbs are great And I would highly recommend them

What I like about it was was the right size. What I dislike about it was the price.

Works good. Reptiles soak up uvb. Remember to change once a year

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

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

I can never find this size in stores. I think the price is decent, too. Any higher then Id just switch over to the standard 18.
