I have just purchased an OZ Bright Heat and UV light. (One of the ones that produce both heat, UVA and UVB.).
The only problem I have, is that it says on the box, "Not suitable for small enclosures & not to be used with a thermostat".
The small enclosure is not a problem, cause I've got a 6ft long enclosure, but the thermostat is the problem.
Does anyone have any ideas as to why I can't use a thermostat, and how I can get around not using it. I don't wanna cook my dragons!

Ive used the lights in an enclosure about 4 foot long without the thermostat for day times and with a decent ventilated cool end you should have no dramas with cooking your dragons. The enclosure that i used it in is now being used in the exact same way with ackies and still no dramas and considering the enclosure is completely sealed with only ventilation at the cool end it runs perfectly.
The reason you cant use a thermostat is cause the bulbs cant turn back on straight away after turning off, something to do with the element/bulb needing to cool before it can come back on to prevent damage to the bulb.
6 foot seems plenty big to run the light constantly for daytime lengths at the hot end. So long as the cool end is easily accessable and alot cooler than under the light, things should be fine.

You can of course put it on a timer... just not a device that is going to turn it on and off all day like a thermostat.
I would be setting it up and monitoring the termperature (with a good Min/Max thermometer) before putting the animals in.
(The same applies for the Aussie Sun Mercury Vapour Bulbs available from the Herp Shop.)

Another thing to consider when using mercury vapour bulbs or any UVB/UVA bulbs is the height at which you position the tube/bulb, the max distance away from the animals basking spot without the aid of reflectors would be 12" (300mm), however depending on the species being kept, you might want to use a reflector or bring the animals basking area closer to the tube/ bulb.
In the case of the mercury vapour, you have to be careful, as they do produce alot of heat close up and alot of UVB, too much for some species.

i was looking at them as a good light sourse in the 3ft x 2ft x 2ft enclosure i am planning on building. i would prefer to have some sortof dragon preferably central netted. will a oz bright make to much heat? the only reason i liked it as it would be easier to run instead of a heat lamp and a floro uv lamp. your thoughts?

| As soon as I got this one up and running and worked out what the best way to handle it all, I'll let you know, and send you some pics. Just PM me with your email address, and it'll be on it's way. Quote:

| I just got one, and there is a sticker on it to say that you can't use a dimmer switch. As as I have been informed by Teamsherman (thanks Matey), it's because the element in them can't keep turning on and off. It aparently needs time to cool down before it's turned on again.

| I liked this idea too Andrew, which is why I thought I'd give it a go. Makes sense. Our enclosure was set up so that the UV was one end, and the heat lamp the other. (Silly, I know). So they were either getting UV, or heat, but not both. Just seems logical to let them have both at the same time.
Will keep you posted on how it all goes.

Hi Amanda, here's a couple of pics how I have one of mine set up. This is the hot end of a 6x2x2 enclosure and the face of the globe is approx 20-25 cm away from the surface of the log it is aimed at. this gives me a basking spot of 40 odd degrees with the substrate level being around 35 deg ambient. the cool end gets to around 26 deg. the enclosure only has two standard 20cm wall vents on the back wall and I am very happy with the results it gives me  If you are in Melbourne you are more than welcome to drop in for a look. I have a couple set up in different ways and they both give good results. You can not use them on a stat and you can't use them on a dimmer. I use both of mine on a timer to come on and off at the same times as the main room lighting. for night time heat I have a ceramic in one enclosure and a heat tape in the other. I bought all my gear through the Herp Shop and everything works fine and was reasonably priced.
Hope this helps?

Andrew, The manufactuers of the floro tubes may say replace every 6-12 mth's, but you would be surprised how much longer some tubes do last, I am talking years, but if you haven't got a UV meter, and don't know anyone that has, then air on the side of caution and replace regularly.
