Zoo Med 24 Watt T5 HO ReptiSun 10.0 UVB Lamp, 2pk

I have been using these bulbs for 5 years now for my bearded dragon. This month, I ordered replacements and I noticed they were giving off a slightly purple color instead of the normal bright white color. I reached out to ZooMed customer service to find out if this was a fake or if they made changes and this was the response I received: "Thank you for reaching out! I apologize for the confusion, but rest assured there is nothing wrong with these bulbs. You actually have the newest version with an improved UV spectrum. Here's more detailed information about the improvement and why it looks different: The main purpose of our ReptiSun T5 line is to provide your animals with beneficial (but invisible) UV wavelengths that are critical to your pet’s health. We continually work to refine the UV spectrum to better match the best light source out there – the Sun! In the latest update, they increased the (invisible) UVA2 output so that the overall UV balance (UVB to UVA) more closely aligns with natural sunlight. To achieve this, a small amount of energy was shifted away from the visible spectrum, which makes the bulb appear warmer, or more reddish, to the human eye. This tradeoff is well worth it, as the improved UV balance better supports hormone regulation, natural behaviors, and activity levels in your pet."

Lizzy loves it!

Great product fast shipment

Measured them with my 6.5R and I got the UVI output I needed. I was a bit concerned because there is something loose inside but they work anyway.

perfect

Exactly as ordered. Nice that you get two for the price of one at the pet store

UVA and UVB light output are essential for the healthy lifestyle of many reptiles and amphibians. These two types of ultraviolet light each play distinct roles. Our Bearded Dragons have thrived under these lights, maintaining a happy and healthy lifestyle. It's important to research and understand the specific lighting needs of your pet, as well as the correct placement in their enclosure, to ensure they receive the maximum benefit.

This is the brand that we have used for our bearded dragons, and our oldest bearded dragon just made 11. Highly recommend.

First bulb of the two-pack worked great, no concern. Six months later, I went to replace it with the second one from the pack and it won’t fit! See the pic I posted, the new one on the right is just a little longer, enough to not fit into the ballast. Of course, since it has been almost a year, I can’t return it. I don’t even understand how that even happens. Aren’t they manufactured based on specs…

T5 bulbs are supposed to last between 6 months to a year. Mine hardly lasted 2 months before it burned out and short of removing my one functional bulb (which I can’t do because my reptile needs it) and shipping both back at my expense for a refund, Amazon wouldn’t do anything about it

Only one light worked out of the two. Not happy.
