Bright light

Postby Rubble1212 » Thu Mar 26, 2020 3:01 pm

Does anyone else have a bd that doesn’t like really bright tank. I have a megaray and I added a 6400 k fluorescent tube that spans the whole tank and he always basks when I just have the megaray on then around 9am or so I’ll switch on the daylight tube and just seems irritated by it?

The 6400k bulb may be putting out a weird spectra. Do you know the spectral analysis of it's output? Or it's lumen output?

Either way, if your dragon doesn't seem to like it, it's probably best to avoid it. This is where watching and knowing your dragon comes into play. You make decisions on husbandry based off your specific dragons needs :)

It’s a sun blaster t5 light for growing plants I thought it would have a color the same as sunlight? Maybe not.

Oh it definitely doesnt. We discussed it a thread in the advanced discussion lighting section. It has a pretty horrible spectra graph if your goal is to mimic the sun's spectra. An ok spectra for growing plants though.

So I’m better off with the megaray by itself then.

What kind of t5 can I get for additional lighting that has a good spectrum.

There really are no good t5s that I've found that have near sun spectra. A few leds I've found but they are expensive and I've obviously not tested them. Believe it or not, but a typical incandescent bulb has a pretty good visible spectra.

Is there a specific reason you're trying to add more light to the tank? Is it too dark?

That's one of the reasons I typically like a heat bulb in conjunction with a long tube uv bulb as opposed to an MVB. the tube uv provides plenty of light.

If you just want light I'd just put another low wattage bulb over on your cool side.

Yeah just more light is all. I have a reptisun t5 but the only basking bulbs i have are a 90 watt halogen flood that gets up to 120 even when it’s almost 2 feet from the basking surface and a 65 watt br40 that only has 500 lumens which I thought was bad? Would you dim the halogen or use the br40? Thank you for your help. I’ve been going back and forth trying to decide which setup I like either megaray or reptisun. I wanted to go with reptisun but I’m having trouble getting the basking bulb dialed in. Also the basking dome is several inches in front of t5 fixture so it doesn’t get the fixture to hot and when the recommended distance is from under the bulb how do you account for the basking surface being 4 inches in front and 12 inches under.

In my tanks I only use a br40 and a t5 reptisun/arcadia.

Sorry... just the opposite in my case. For a while I had to mount the basking light in a clamp-on fixture. ZaRDoZ tried several times to attack/jump on the bulb. Never did figure out why, unless he didn't like the brand of bulb or something (it's just a household incandescent flood). Now that it's recessed in the ceiling, he looks/stares at it once in a while, but he doesn't try to attack it anymore. :dontknow:
