SUNBLAZE 44 LIGHT CHART FULL
The idea is to provide behavioral enrichment, and to not expose the tortoise to a full 'daytime' of the UV's.
This distributes the UV exposure to different times during the first timer's 'light' period, but in two hour events. The first one is for the regular ON/OFF of 12 to 14 hours of light/dark, while the second one is programmed to run for two hours at a time with the UV plugged into it. I've also recently seen an idea on FaceBook where the person had two timers in series. the produce less heat and more light for the $$. I have begun to use the Arcadia Shade dweller, as it works well in close proximity to the tortoise (low ceiling), and I am converting all 'plant and ambient lighting to cool (5000 to 6000K) LEDs. That the fixture you bough has or does not have the anti-fire coating that originally brought this whole question up is not resolved here. So, S your SunBlaster may or may not bee a concern, the breadth of the refection may be even more intense than what Mark has shown relative the the Arcadia fixture, but it is not A SunBlaster in the comparison, but a SunBlaze. You can see, I hope, it is half way between the two for the width of the reflector. These are not the best comparative images, but you can see that the Arcadia fixture more or less are the same as the the SunBlaster, a narrower focus, while the SunBlaze does throw the light in a much broader area, as Mark says, to support plant growth. The whole of my interest here was Fran Baines (sp) noting on the 'Reptile Lighting' FaceBook group that SunBlaster had changed a coating on the Mylar reflector to make them more 'fire safe' and that the coating significantly reduced the UV chart such as the one you produced here. Maybe I've had a good system using the SunBlaze and the closer distance. I use 18 inch tall enclosures, and with a few inches of substrate and a few inches of space to hang the fixture I end up with the tube/reflector about 10 to 12 inches from the substrate, so a bit less once you include the height of the tortoise.īTW, I believe I sent SunBlaze, not SunBlaster I think I recall that you mentioned somewhere that it seems possible that UVA is 'over' produced relative to how tortoises behave and the penetration of the UV's. The plot area shown is 30" long by 22" wide The fixtures are both the 22" T5 fixture. It is a new bulb with only a 1 hour burn in time, but I do not see substantial changes in those bulbs after an hour. The same T5 12% Arcadia bulb was used in both fixtures. But at the 18" level, it does provide a great, wide basking zone. Because the fixture reflector is focused, the UVB is much greater and not usable at the 12" distance as it is too intense.
SUNBLAZE 44 LIGHT CHART PRO
The Arcadia Pro T5 does provide a more designed basking zone and focuses the light into nice gradients. At 12" there is quite an increase if the tortoise can get to 8" for example. I would not use it with a tortoise that is not small and its positioning could bring it or its eyes closer to the bulb. At the 12" height it does give a nice broad pattern of UVI in the 2-3 range that is quite useful in an enclosure with limited height. This is great for plants as you can light a larger area, especially when not dealing with UVB output. It is designed to fan the light into a broader pattern without the focus of the Arcadia. You can immediately see the Sun Blaze is not made for reptile basking, but for Plant lighting. Thanks to a reminder from Will, I got the data out and did the plotting and graphics and can now post the results in an easy to see format commonly used in comparing bulbs. Unfortunately translating that to a easily interpreted chart takes a bit of work and it got shoved and lost on the back burner for a while. So Will sent me a Sun Blaze and I did a plotting of the UVI output at both 12" and 18" exactly from sensor to bottom of bulb.
I replied I did not but would gladly do a test comparison with the Arcadia brand I use as a standard. Will had come across some Sun Blaze fixtures that looked promising, so he asked me if I had experience with them. My reptile show partner, Will - Farms and I were looking at various options for sources of fixtures for UVB lights. But even the better brands vary tremendously. I am not even discussing the less expensive hardware brands of T5 fixtures as they are not at all reliable in my opinion.
A different fixture with the identical bulb will give totally different reading and require different mounting heights. One variable is the type of fixture the bulb will be used in. They are somewhat pricey so many go without, However, advice then given may or may not be accurate at all. The problem is there are so many variables it is only solved by the use of a Solarmeter 6.5. People often ask how high they should mount their UV bulbs.
