Zoo Med PowerSun UV is a self-ballasted mercury vapor bulb with two main components. The first is a standard incandescent filament, which is the first to light. The second is a mercury vapor arc tube, which takes a few minutes to heat up. There will be a noticeable change in hue (or color) when the bulb is completely warm and fully functioning. Because the PowerSun UV is a self- ballasted bulb it can be used in any ceramic socket that is rated to handle the wattage.
Zoo Med PowerSun UV has nickel-plated threads to ensure that it will not corrode in humid reptile habitats. This new bulb also incorporates a short neck design, unique among mercury vapor lamps, that allows it to better fit into "clamp lamp" type fixtures. PowerSun UV projects useable UVB radiation...

This blub in combination with the 10" ceramic socket makes alot of sense for reptile habitats. I use this bulb on my 29gallon turtle aquarium. Though initial set-up is more expensive than a normal heat lamp plus florescent UV light fixture. In the long run, this high quality, long lasting blub has saved me money. Where as any brand of 100w heat bulb I would buy would die within a month, this bulb is still going strong after 6 months, and is rated to have high UV output for up to a year!!!

I like the fact that you can use 1 light for heat and uvb rays, and eliminate clutter, thanks!

This is a really good bulb. It seems like it lasts forever!

Provides both heat and UV light for our bearded dragon. Saves us money vs. buying both heat lamps and UV fixtures + replacing heat bulbs every three months. This bulb lasts between 1 and 2 years depending on use. Couldn't be happier.

Love this bulb! My turtles sure do enjoy basking under this lamp. I used to have a regular fluorescent tube with a 100W light bulb in order to provide my turtles the UV and heat sources, which was very clumsy. With this bulb, my turtles can enjoy both the UV light and heat evenly distributed from 1 source.
I highly recommend it to all turtle lovers out there!

I have used these for several years and they always work great. I usually change them after 1 year of use, but recently I let one run for 20 months and it is still going strong. You should remember to replace them, though, because UV output does decrease significantly after 1-1.5 years. They may be a little expensive, but these are essential to the proper care of your turtles!

I have two turtles (water turtles...aka red eared slider turtles and I didn't want to get them a basking lamp so I got this instead and they love it. They are very active and they use it not only for uva and uvb but also for heat because this bulb gives off heat too... I recommend it to anyone.

I like the fact that I only have to buy 1 light for heat and uvb rays, the cost is more but it last twice as long.

I've used this bulb for over a year and it's still going strong. You can't the beat the value.

I have used the power sun vapor bulb for my tortoise for several years and it works great for his environment. I usually order from Zoo Med as the quality is good and the price is always better than the other stores that handle the bulb.
