100W Full Spectrum UVB UVA Sunlight Basking Heat 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.

Great dual bulb! This is the only bulb I use for my turtles Oasis. She’s in a 4ft x 4ft x2ft living space and this hangs over her custom 🐢 island.

Excellent light works very well and I have even seen my leopard geckos come out and bask more often

Used less than a week and light burnt out. Turned on and off every 12 hours, never moved. **UPDATE** The seller contacted me and offered to replace the bulb. Have used this brand before without issue. Will continue to, I will just buy at the store.

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

Price a bit high.
