Heat lamp and galvanised wire mesh

Vishnu&Archibald said:

Hello everyone,

I need to make a lid for my indoor enclosure, there will only be about an inch of space between the UVA/UVB bulb and the wire mesh. It is a 150 watt bulb. Is this an overheating or fire risk? If so, is there any kind of paint i can use on mesh to remove or decrease the risk?

Thank you!

1. Basking bulb. I use 65 watt incandescent floods from the hardware store. Some people will need bigger, or smaller wattage bulbs. Let your thermometer be your guide. I run them on a timer for about 12 hours and adjust the height to get the correct basking temp under them. I also like to use a flat rock of some sort directly under the bulb. You need to check the temp with a thermometer directly under the bulb and get it to around 95-100F (36-37C).
2. Ambient heat maintenance. I use ceramic heating elements or radiant heat panels set on thermostats to maintain ambient above 80 degrees day and night for tropical species. In most cases you'd only need day heat for a temperate species like Testudo or DT, as long as your house stays above 60F (15-16C) at night. Some people in colder climates or with larger enclosures will need multiple CHEs or RHPs to spread out enough heat.
3. Ambient light. I use LEDs for this purpose. Something in the 5000-6500K color range will look the best. Most bulbs at the store are in the 2500K range and they look yellowish. Strip or screw-in LED bulb types are both fine.
4. UV. If you can get your tortoise outside for an hour 2 or 3 times a week, you won't need indoor UV. In colder climates, get one of the newer HO type fluorescent tubes. Which type will depend on mounting height. 5.0 bulbs make almost no UV. I like the 12% HO bulbs from Arcadia. You need a meter to check this: https://www.solarmeter.com/model65.html A good UV bulb only needs to run for 2-3 hours mid day. You need the basking bulb and the ambient lighting to be on at least 12 hours a day.

Hi Tom, thank you for the info. What is it about the mercury vapour ones that are unreliable/unsafe? I tried to find more info online but couldn’t see anything

It’s best going with a separate uvb and heat set up, having combined heat and uv, means when adjusting your height to create the desired basking temperature, you’re messing with your UVI zone, they are much more desiccating on the shell and their uv output often very unreliable.
There’s the added fact of uv timing, with the uv timing, every other source of information will tell you 12hours of uv. This is essentially an old fashioned rule that has stuck with a lot of keepers, it stems from the presumption that once the basking light or ambient lighting is on, ie the ‘sun’, that uv must coexist the same amount of hours. Fact is, uv rays only peak for a few hours a day, anyone with a uv meter will confirm this. No tortoise is blasted with 12 hours of uv in the wild, therefore it’s not necessary in captivity. Whilst not necessarily dangerous, it’s potentially annoying to the tortoise to have 12hours on uv in the enclosure.
The right uv bulbs are much more expensive to replace once their uv strength diminishes, so it’s definitely best having it on a 4 hour timer that provides them with all the uv they need, saving your bulb life.
Then some cheaper led lighting for your ambient 12 hour light cycle as well as the basking light on the same 12hrs, your ceramics(if needed) will run 24/7 on a thermostat, hope that all makes sense
The most recommended up to date indoor uv option is t5 tube fluorescent bulbs, they disperse the uv light over a much wider area. Recommended brands are Arcadia proT5 kit 12% or zoo med reptisun t5 10.0(hood usually sold separate)
