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. 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. One year warranty on lamps.People often ask how high they should mount their UV bulbs. This high-quality light source provides excellent, on-target light output. Using the environmentally friendly, mercury-free AgroLED® iSunlight® lamps reduce electricity consumption by up to 25% compared to traditional T5 lamps. The daisy-chain feature allows multiple fixtures to be plugged in together. Eight lamp model features two on/off switches to run four lamps at a time if desired. 12 ft power cord and on/off switch allow for easy operation. Wire cable hangers are included with every fixture as well as V-hangers and hanging holes for side mounting (hangs horizontally or vertically) and lower ceilings. White powder-coated steel housing is louvered for cool operation. Sun Blaze® LED fixtures feature an advanced reflector design that delivers excellent reflectivity and diffusion. These lamps combined produce an amazing 2,400 lumens per lamp for 2 ft and 4,900 lumens per lamp for 4 ft with a 5,500° K lamp color that is ideal for propagation and vegetative lighting cycles. This high-efficiency T5 LED fixture is equipped with 21 watt AgroLED® iSunlight® lamps.
