## Description

Product Description Many species of Reptiles and Amphibians require a warm spot under which they can bask and become fully energised with heat and Ultraviolet. As in nature, these basking zones should be UV rich and stable. Therefore, this lamp is available in three sizes: 80 watt, 100 watt and 160 watts. The Arcadia D3 UV 100w Basking Lamp provides UVB, UVA visible light and heat. This basking lamp aids the synthesis of Vitamin D3 and helps to prevent metabolic bone disease with the UVA increasing feeding, mating, and other natural behaviours. This D3 Basking Lamp can be used for many species of reptile including Bearded Dragons, Tortoises and Iguanids!

Review: Great bulb for heat and UVB loving animals - i have the 160w version on my larger viv and that is a great bulb the light is very bright and more of a cool white color. but the 100w version that i just purchased for my 4ft viv is the same dull nearly orange color. not really a big deal but just wanted to let you know the difference. the 100w performs great and my tems for my uromastyx are spot on. its great knowing that my animals are getting UVB as well as heat. also this has a 12 month warranty so i can feel confidant that this is replaceable should it die whiles in service in that time frame. you may find that your standard bulb cage will not fit as this bulb is big in size almost 2.5 times bigger then the normal ones. no bid deal for me as my lizards cant reach it. but just in case you have decorations that your lizard can reach the bulb you may have to look in to getting a bigger cage guard.

## Questions & Answers

**Q: Are they not offering a bayonett fitting of this bulb now?**
A: As far as I know it's just screw in as most fittings require the screw type bulb

**Q: Am I right in thinking it's screw in as opposed to bayonet fitting?**
A: Yes it's screw in but you must use a ceramic bulb holder because of the heat, a normal plastic one will melt.

**Q: Does this provide turtles with UBV as well?**
A: Yes it does and we do have it in stock. Thank you.

**Q: Do these lamps still come with a guarantee?**
A: Hi Beth, they do come with 12 months warranty. Anguel
