Zoo Med PowerSun UV Mercury Vapor UVB Lamp Reptile Incandescent Bulbs at Pet Mountain

Mercury Vapor bulbs might seem a bit expensive, but they are very worth it! This one is great! I have been running it for a long while now with no problems. It has auto-safety built in to keep itself from over heating. Really brings out the beauty in my Caiman Lizard and he loves to bask under it! Much easier to achieve the right basking length in tandem with heat when your bulbs are one. Just be careful not to mist the bulb directly in high humidity enclosures or you risk cracking and shattering.

My first PowerSun UV 100W bulb only lasted 1 month. My current bulb has been working fine for 11 months. Would be nice if they'd offer free return shipping. It does take several weeks to get the item.

I love these bulbs since the are both heat and UV in one. They are a little pricey, but my bearded dragon and tortoise love them!

Bought this for my RES' basking lamp. After three and a half months the bulb is dead. Considering the manufacturer claims "over 2 years with normal use," I'm pretty disappointed with it. Since I also purchased a single lamp fixture, and therefore need a heat/UVB bulb, I'm kind of stuck with 3 options. This lamp, the T-Rex lamp (which is always out of stock, and the Mega-Ray, which is also hard to get. So unfortunately I guess I'll have to suck it up and buy another one of these. It's unfortunate that Zoo-Med can't make a better product considering they're pretty much the only game in town.

I use the PowerSun 100W for my Panther Chameleon--and I admit I used it past the recommended 12-month replacement schedule. But that only speaks to the quality of the bulb. At about 18 months it was still working, but I could notice the intensity was not as much as a new bulb so it was time to replace. I bought a new one from Pet Mountain where I had bought the first one too--best price available.

I purchased this bulb and it worked one day. I sent it back which cost me $9.00. I received my free replacement and it only worked a month. I sent it back and it cost me another $9.00. Like a dummy, I purchased another because I didn't want my bearded dragon to be without a uvb bulb, and hoping I might get a good bulb that worked. This is the last time I buy this bulb from zoomed. This isn't a cheap bulb and they need to figure out why these bulbs are not working properly. In the mean time, I will be trying to find a decent bulb that works.

Absolutely love the the zoo med light -don't go with any other brand. Tortoises love to hang out under the bulb.

I usually use T-Rex but they were/are out of stock so got this in November 2010. I have a UV meter and it is no longer emitting any noticeable UV, my 2 year old strip florescent is reading ~55 and this bulb is only 22. Don't be fooled, it comes nowhere near the 2 year life claimed. Light and heat, yes; UV, no. Now I have to track down a T-Rex for my tortoise's well being.

This product is extremely good and hands down the best bulb ever,just make sure you have the proper light fixture and it will work wonders.

Was going to buy it at petsmart for 80 dollars for my new bearded dragon, saw the same thing on here for 40, and it works great!

No more basking lamps and UV light...now they're all in one. There is much less clutter. I love these bulbs.

On September 12, 2010:
I had some other brand of uv bulb and it went out in two weeks. I took it back to the store got the same one, same thing happened.  Then I got the PowerSun, loved it and never went back!

On September 6, 2010:
I am happy to see that there is another product available that does two things in one product. The price is great!

I use this bulb for all my diurnal reptiles! I love it! It's so nice having just one bulb for both the UVB and UVA!

On August 11, 2010:
A great bulb for both UVB and heat. I have been very happy with the quality of the bulb. Buy it, you won't be disappointed.

On July 19, 2010:
This lamp lasted almost two years. When it did go out, I went to my local pet store but didn't have the zoo-med brand. I bought another brand and it last ONE month.That was the 2nd one. The Zoo-Med is the BEST....

On June 9, 2010:
This is an excellent all in one product at a terrific price. The built in safety feature of turning off when the temperature gets too hot is amazing. This works great for maintaining the proper temp for my Argentine Tegu and reduces the need for multiple light fixtures.

The Powersun gives my bearded dragon everything he needs for UV and for heat. So much easier to use a single source for both. I do have a second heat bulb simply because the enclosure is 4' x 2'. However, the PowerSun is so important I keep a spare on hand so I won't be without.

On January 17, 2010:
We are very pleased that Pet Mountain has such a broad range of products and that the prices and shipping rates are good. Thank you Pet Mountain!

The safest UVB available for reptiles! Very reccommended! Normally $85!!!

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.

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

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 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.

This is the most awesome light to use on bearded dragons. they love it and it is better for their health and is cheaper than buying all the other stuff. This bulb is the best!!!!

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!

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!

On June 3, 2007:
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.

On May 27, 2007:
This is a really good bulb. It seems like it lasts forever!

On May 21, 2007:
I like the fact that you can use 1 light for heat and uvb rays, and eliminate clutter, thanks!

great bulb!

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!!!
