  • High quality German bulb


Emits UVB a full 20/51cm from the surface of the lamp to prevent or reverse metabolic bone disease. (Compared to 12"/30cm on the ReptiSun 5.0). Optimal for use with larger terrariums where greater than 12" of UVB penetration is needed. The ReptiSun 10.0 is also recommended for use above screen covers which can filter out up to 50% of the UVB wavelengths."

I guess I'm cheap (or poor, which might be what makes me cheap), but I just find it a bit hard to consider a single bulb worth $20+, but then again the price isn't what I'm reviewing.I bought one of these bulbs before, and with these type bulbs you must replace them (even if they aren't burnt out) at regular intervals of about 6 months. They will continue working, but not producing UV radiation at the required levels.I've been using them in my bearded dragon's tank since October 2011 and he's still doing fine. The bulb works and does it's job, the lizard is healthy, it arrived well packed and padded to heck and back with bubble wrap (which I appreciated). I can't see a reason not to give 5 stars.

This is a great UVB bulb for any reptiles. I've used these bulbs for over 6 years with my Iguana and Tortoises and they have both stayed very healthy. Due to the cold weather throughout most of the year I have had very little opportunity to provide natural sunlight and these bulbs have made up for that very well. They have always lasted 1 year (at which point I always replace them as their UVB output drops off significantly) and have lasted well even in the high humid enclosure which houses my Iguana. Great UVB bulb!Amazon's Price for this item can not be beat at any local store though I always check.

This is great, I got the product in less than two days with the amazon prime deal and the product was superbly packaged, nothing broken. Couldn't have asked for more except the fact that this bulb showed up in a search for t5 HO UVB but is in fact a t8 bulb....no where had I read that it was a T8 so I ordered it. Not that big of a deal, just left me a bit miffed.Ordering the T5 rit after posting this, Kalisti! It's like I'm a amazon addict. -.-

One of the best UVB bulbs on the market. The one petshop I found that had these wanted $50 for it so buying it off here saved me a great deal of money. I was worried about shipping a bulb as they are fragile but it made it in one piece due to great packaging on there end. I purchased a standard housing for it at Walmart (about $10), took the plastic cover off (less obstructing of UVB) and mounted it inside my 40 breeder tank. Definitely will purchase again as they are to be replaced once a year.

First time I received this bulb, the seller apparently had no idea how to correctly ship it, and I received it entirely shattered inside it's box. The second time the bulb hadn't shattered, so I stupidly assumed the bulb was safe and never bothered to test it out in my fixture. I wrapped it up in my own bubble wrap and put it in my garage.Went to replace my tortoise's bulb yesterday, and this second bulb isn't working either. Both ends of the bulb are getting really bright but the bulb won't turn on, just flickering. Tried to contact the seller because this replacement bulb wouldn't work at all and they're mega expensive bulbs, and the seller basically told me it's been too long to do anything, so they incorrectly ship these bulbs in the first place, and then even though it had been over 30 days before I became aware of the fact the "replacement" was also defective, they have basically told me I just have to buy another one. Don't buy from these people they don't know what they're doing with expensive bulbs.

Thank the gods for amazon. The "competetor's" inferior product at petco is nearly double the price of this. And they don't even carry Reptisun at my local Petco OR petsmart, which have officially run all of the decent locally owned pet shops out of town.If you're going to take on the responsibility of caring for another living thing, do it right. Spend a few extra bucks to get them the right stuff, their quality of life depends entirely on you and your choice to adopt them. For a bearded dragon, there is no substitute for the ReptiSun. Remember to replace your bulbs once every year or two. Just because the light hasn't burnt out, doesn't mean that the UVB production is still working. Every 3-6 months as recommended is excessive and unnecessary. Just a ploy to sell more bulbs. There is no evidence that the degraded UVB a year or more into a bulbs life is insufficient. But to play it safe and ensure that an indoor desert lizard such as a beardie is getting as beneficial a habitat as possible, I recommend once a year, two years tops.

I purchased this for a tank for my bearded dragon. The bulb in the fluorescent fixture had burned out. I had an interesting problem with this light in that it didn't fit well in the fluorescent fixture for my tank. It was a little too long and the prongs would not slide into the slot - I had to snip off a small length of the prongs to get it to fit correctly. After getting it installed it worked fine.

It’s the only brand I use. Never any issues.

ホルスフィールドリクガメのケージ照明に使用しています。しっかり明るいです。ＵＶ量も問題ないようで、甲羅が柔らかくなる、骨が変形するなどのクル病になることなく10年以上飼育できています。明るくても1年で照射されるＵＶ量が減るそうなので、うちでは年一回交換しています。

Die bisher beste UV Neonröhre die wir hatten. Gsd wird die Technik immer besser und weißes Licht ist wirklich weiß.Besonders wichtig für Wüstentiere die bei zuwenig K-Leistung statt weiß immer wie durch eine Sonnenbrille schauen.Die UV Leistung selbst scheint gut zu sein - kann man selbst ja wenig messen - aber die Tiere sind mega aktiv und fressen und kacken wie die Weltmeister (im positiven Sinn). Aktivität und Verdauung und auch Häutung mit diesen Lampen perfekt.

Really good ! Only took a few days to arrive and it works really well. I recommend this product to everyone that own desertic animals that need powerful lights ! But you HAVE to change this light every 12 months.
