100W UVA UVB Reptile Sun Lamp

So far, no issues. Good value to cost ratio! I have purchased the name brands in the reptile industry at much higher costs. I will update the review should circumstances change. It is imperative to understand the inherent properties of a mercury vapor bulb before your expectations are determined. 1) MV bulbs generate a lot of heat and are intended to be used with open, wire cage type light fixtures. The exception would be a large, high dome fixture. Excessive heat in a small dome fixture is detrimental to the life/performance of the bulb. 2) The bulb has built in safety features. If you turn the bulb off and then on again, it will not immediately light up. It will take a few minutes. 3) If the bulb is on and gets jostled or bumped around, the light will automatically turn off. Again, another safety feature. Wait approximately 10 minutes and it will illuminate on its own again. I cannot discredit negative reviews/experiences with this product. However, I must consider that the above mentioned phenomena could be relevant. I hope this information will be helpful when you set your expectations.

Update!!! Company contacted us and sent a replacement bulb. New bulb still working good, great customer service will recommend and use again. Thank You!!! Bright warm bulb used for our tortoises but burnt out in one week. I ordered a replacement hopefully that one lasts longer. Reordered because of good reviews. Will review new bulb in a couple weeks

I've got this on a cage Im growing out some baby iguanas in.... The first picture shows a size comparison - they were all +/- maybe a third of each others size and a couple of them have grown A LOT faster so thats whats up with that- What it does tell me is that they are growing and the conditions are right ( why some grow faster - no idea.... I got these things wild caught from UGR so who knows) As others have said do NOT enclose this bulb. I have it open to the whole cage in a mesh guard and screen top above it. You do not want to enclose it because during the day this bulb alone can put the area around it near 100F- I have a heat emitter on a thermostat which comes on basically only at night to keep it from getting too cool on the warm side - because this thing does double duty as a space heater believe me . Thats a GOOD thing, you WANT a hot basking area- you almost cant go too hot unless youve got this light close than 10" to the animals- But dont cook them and make sure they have a nice cool side - for some reason a lot of people have not figured out the sun/shade dynamic with their reptiles which they would have in the wild and they rely on. overall though the bulb is decent for the money, its def putting out UV and the iguanas are growing and basking and using it. I have another bigger version of this bulb I use on a bearded dragon enclosure and its ALSO good so far but I've had it for less time so I am waiting before I review it.

It's working but not sure if the light is working correctly. It's not very powerful.

Lasted 2 weeks. He loved the warmth of it while it lasted.

Quality product at a great value. Necessity for reptile lighting needs. Highly recommend!

Despite being snapped at when I asked why this bulb can *only* be used for reptiles, I decided to give it a try anyway. (Other Amazon customers stated this produces way too much heat to be used for anything other than reptiles and therefore I should not use it for anything other than a reptile.) I have a few indoor ducks who don't get enough sunlight, especially with the current strain of avian influenza going around. I wanted a UVA/UVB light for them since they're not getting much natural sunlight. They weren't particularly impressed by this light at first which isn't surprising because they're rarely impressed by new things. My cats and dogs were all very impressed though and would spend hours basking under the light in the area I had set up for the ducks. The light does produce a bit of heat but I definitely wouldn't say it's hot under the light. It feels very similar to the heat from a sunny window. Warm and cozy but not hot. Since the ducks weren't using the light I decided to try laying under it myself to see if it was too hot... obviously I don't want to accidentally roast my feather babies and since Amazon customers had basically stated this is what I was going to do, I needed to see for myself. I determined the Amazon customers were wrong. Anyway. I used the UV tester cards to be sure this was producing enough UV light, or any UV light. (other UVA/B bulbs I've purchased didn't actually produce any UV light.) The card turns purple very quickly. I'm quite impressed.

Lights work great for my reptiles enclosures.

Price a bit high.

Decent price and delivery. Works well with my bearded dragon setup. Good lifespan but I would always prefer more.
