Hi!Well you’ve well and truly scared me that’s for sure, but thank you for this information. I do not have the box for the lamp, stupidly I threw it away. He’s light has just come on, so not sure if you can see the photo of the bulb properly, but they said to me that it’s an all in one bulb and I didn’t need anything else. This is also Arcadia, everything I had was that make. Currently this is a 4ft box, I was told he’ll eventually need a 5ft box. So should I buy him an enclosed glass tank?
Orchid bark, not a problem I can get that straight away. Water dish I can change.
The lamp you have if it's really all one one - is a mercury vapour bulb (MVB). While on paper they look great, in fact they don't:
1. Hard to balance basking zone size, temperature and UVB level (you can't adjust only one of three) and use basking light/UVB on different timers.
2. Relatively short lifespan (only 6 months) until UVB output fades below useful.
3. Some evidence, that output spectrum of these lamps is desiccating and contributes to shell pyramiding.
So the idea to have separate basking and UVB light definitely makes sense. Even with higher initial cost, it's cheaper in the long run and provides more healthy environment. Here is what you need (check SwellReptile, for example, for ordering):
1. Get Arcadia Solar Basking Floodlight (not Spotlight). 75w is a good start. It's around 7-8 pounds and fits your existing lamp dome. Set on 12hr timer.
2. Arcadia ProT5 Desert 12% kit, 24W - it's between 50-80 pounds. Set on 4hr timer. This lamp is expected to work for 2-3 years. Lamp should be mounted at 18-21 inches above substrate. Preferably to make adjustable height (UVB fades out with time and you can lower the lamp to compensate this).
3. Any simple LED light source for ambient light (bulb or LED panel/strip/tube).
4. A bit later - ceramic heat emitter with a thermostat to sustain ambient temperatures at 75F (24C).
4ft. enclosure will last for a 2-3 years. It's easier to think in square ft., just in case - 8-10 sq.ft. for babies and yearlings and around 30-40 sq. ft. for an adult tortoise. No need to order tank or vivarium, just get a portable greenhouse to enclose whole enclosure.
