Re: Large Enclosure Ligthing
- Hi, Targ.
24 watts - 61cm (22 inch) tube
39 watts - 91cm (34 inch) tube
54 watts - 122cm (46 inch) tube
> What distance you think i could get from the tube? 50 cm with the reflector?With one tube in a reflector, 50cm is a bit far for really good levels of UVB in the basking zone. But two tubes mounted together above him, would do it easily, as you literally get twice the UVB... you'd expect a UVI of 4 - 5 in the zone about 50cm beneath the two tubes.
If you can find a distributor, two of these would be perfect:
(they can be screwed to a solid roof of a terrarium, which would solve the problem of Cyan trying to climb onto them as they'd be flat against the roof and offer nothing to get a foothold on)
or two of these (but with the glass front panels removed):
or maybe this double unit:

(In USA) http://www.lightyourreptiles.com/24hot5dobufi3.html is perfect.
You might find double units for HO tubes in an online hydroponics store, as well.
> by example imagine if i cut a vertical slit on the side of a wall, put mesh and the reflector.No, definitely don't put the tube down the side of a wall. The light should always be above his head, shining down. It should not be at or below his eye level, as this makes the light go straight into his eyes. He would not be able to look in that direction at all, without getting the light in his eyes - like looking at the sun. This could be very stressful, and the UV could even be harmful.
> will that benefit him in any way? they get uvb from the top usualy so i m not sure. the ray would hit him on the sides? but that wall would be flooded with uvb. what do you think?
When light is above an animal (or a person)their upper eyelids shade the pupil of the eye from the light source, this protects the inner eye.
