It works well. I like the long wire. I just have it hanging by the wire over a small shelf. It does the job, good for warmth and healthy reptiles.

I've used these for my red eared slider for years no issues and she has stayed healthy. I want to say reptisun has a bulb reminder online you can sign up for, and it sends an email when it's time to change. Super conveinent they offer that.

My frog is always sitting under it, so I'd say that it's exactly as advertised. Not sure how long it'll last for, but I have to believe it'll last about as long as it says.

Although I typically buy Reptisun bulbs (13 and 26w compact fluorescents and T5 high output tubes ) through Amazon, I thought I’d purchase some Exo Terra Repti-Glo UVB’s so I could compare the two brands. Unfortunately, none of the three Repti-Glo bulb worked on arrival, so I won’t be trying them again (maybe they just don’t ship well?).Last week, I experienced my first issue with a Reptisun bulb. Because Amazon’s 30 day return window had already closed, I emailed Zoo Med directly explaining that the lamp had separated at the base while in use and I sent along a photo of the lamp and a copy of my receipt. They responded immediately and I received a replacement two days later.Although a lot people say you have to replace these every 6 months, I follow the manufacturer’s recommendation and replace all of the bulbs on an annual basis on New Year’s Day. I do, however, keep a spare of each type of bulb on hand in case one burns out mid-year. If you’re new to UVB, beware there’s a ton of old info online saying that compact fluorescent bulbs aren’t safe. While it’s true there were issues years ago, they were redesigned and are safe now under normal circumstances. I am, however, extremely careful to purchase bulbs from reputable manufacturers and distributors only – I won’t buy cheap or generic knock-off brands.I use UVB in all the terrariums, including with corns snakes, as the latest studies/literature indicate that all these guys benefit from some exposure (just make sure there are hides available). I use13w minis primarily in 10 gallon terrariums with inhabitants that don’t require high amounts of UVB (I make sure that they can’t get too close to the the light) in 5.5” dome fixtures which cast a smaller footprint, though I’m also using the same arrangement for my daughter’s diurnal, shade-dwelling lizard whose terrarium is twice as large (it’s in a double dome fixture with his basking lamp). There are some excellent iso-irradiance charts available online that can give you an idea of how far the UVB will spread and what the intensity of the rays will be. Just be sure the bulb is near the heat lamp as reptiles need both heat and UVB for vitamin D synthesis. Also, be aware the if you have a mesh screen top, the finer the mesh is, the less UVB the animal will get (I’ve read that the reduction ranges from 30-50%); however, a reflective dome can focus/intensify the UVB which can make up for the loss-it just depends on your setup). Likewise, never place ordinary glass or plastic between the UVB bulb and the lid- they’ll filter out the rays.I’ve also bought the 26w model for her diurnal snake’s enclosure. It’s installed in a canopy light next to the domed basking light in a 40 gallon breeder tank (36x18x18”), providing a large UVB gradient that overlaps the temperature gradient. I set the UVB to come on an hour after the incandescent and LED lights and it shuts off an hour before they do so Race has an opportunity to bask with and without it present. The 26w lamp, however, was too long for the 5.5” mini domes I buy.All-in all, the mini compact fluorescents are great for smaller enclosures and for those guys that don’t require a ton of UVB or for creating more specific zones of exposure. The 13w lamps also fit smaller dome fixtures as well as canopy tops, but they can fluctuate several dollars in price so you may want to watch the cost. I’ll definitely be buying more.

Bought this for my son. It's been a month or so. So far it's been working great. Created algae in just 1 week; my son said that's good because it means the UVB is strong. I have bought three of these bulbs, two which were from our local pet store. So far, only one bulb completely burned out and stopped working after the fourth month of use. The other one had lasted my son's turtles a good eight months before replacement. Great product, let's hope it stays consistent.

Coil UVBs are NOT good. These bulbs? Great. Even better if you can get the linear bulbs also by Zoomed that go across the entire enclosure. But these will do great if you’re on a budget or have a small setup. Have used these for my two crested geckos, one is 20g and one is 5g, both use the same bulbs (different wattage, though) for each of their tanks. Plan to upgrade to the T5/T8 lights when I’ve got the expendable money but I’ve had no issues so far. Doesn’t get hot, no health concerns for the geckos, great price point, lasts a long time. Solid bulbs! Not much else to say, I recommend these to anyone needing a UVB for a reptile!

Gives turtle perfect amount of light and heat.

Zoo Med ReptiSun 5.0 UVB Mini Compact Fluorescent (13 watts) ~ List Price: $17.99 on sale for $14.74Sold by:the Zoo Med Store ~ Shipped by AmazonLast purchased Sep 18, 2022I've come across tons of articles and forum posts over the years saying fluorescent tubes are generally the best, but they can be overkill for smaller enclosures and more temperate species, and as far as CFL UVB lights go Zoo Med has had the best reputation from the get go.Been using these as my go-to UVB lights for years on and off whenever I'm keeping reptiles and never had any issues with them and my pets are happy and healthy. Nice to get them at a better price here on Amazon as the LPSs charge an arm and a leg. I do wish they'd get around to making these that did the UVA/UVB plus added full spectrum, but perhaps there's something that makes that difficult or expensive. Anyway as far as UVB lights go I've always been happy with these.

Excelente, buen producto

Light arrived and worked well for 2 weeks, then quit working.EDIT: Zoo Med mailed me a free replacement, which is working great.

Work as it should ,

Une bonne ampoule pour le moment fait le taf à voir si cela dure un peu plus que la dernière d'une autre marque...

Good
