Packed with so much care! It was delivered in perfect condition! My lizard was very happy!

Burned out in less than 48 hours. Had to return it.

UPDATE TO MY EARLIER REVIEW (I can't find out how to edit or delete my earlier review, so I'm posting a new one). We have been using this bulb for several years, always replacing once or twice a year. It's very reliable and long-lasting and my reptiles are thriving. My earlier review stated we couldn't get the latest batch of bulbs we purchased to stay on. Turns out it was user error, NOT the fault of the bulb. We were not turning off the fixture before removing/installing the new bulbs (it's a huge tank for our tegu and awkward to get at the switch). Luckily we figured this out and the new bulbs are working great.

I have been using this bulb for years for our lizards, always replacing them every 6 months as recommended. However, this year when I purchased the new bulbs for replacement (from a different online retailer), one didn't work right out of the box. I got a new one and it only worked for about an hour after going out. So I got another replacement, this time from a Petco store, and the same thing happened! It works for about 30-60 minutes before shutting off. I replaced the fixture as well, thinking that was the problem. Nope, it still goes off after working for a little while. I am at my wit's end, I'm not sure what to do at this point. The fixture I bought came with a bulb but it's a grow-light that doesn't have the uvb spectrum my lizard needs. Regardless, this morning I installed it to see what would happen (to rule out the fixture being the problem) and it's still going strong. I don't know if Zoo Med had a bad batch of bulbs that went to several distributors, or what's going on. I may just have to find a new brand if I can that has the same specs and the same size.

Good product, however, not packed well. Placed in a giant box.

This product needs to be paired with a terrarium hood that will fit the lamp. That hood needs to be bought separately. I would recommend buying this product as a replacement only for the sake of spending less money. Great product though :)

Cheapest I can find and always in stock. Local pet store never has more than 1 in stock at a time

I got this product for my bearded dragon. Last one, I bought lasted about 4 years. So hopefully this one will last a while. It was delivered at a timely fashion and well packaged.
