Question 1

is this a full set? Do I have to purchase any accessories for it? how is the uv output?

Accepted Answer

i purchased this and it did come as a full set (bulb and fixture), i did not have to purchase any accessories however i already had the lamp stand so if you do not have a stand you may want to get one as the light must be hung. it cannot sit ontop of a screen. i purchased for a large enclosure i have for a redfoot tortoise and thus far the UV output has been exactly as described by zoomed at the distance the instructions stated - please note that this bulb is an HID so if you have been using a mercury vapor bulb in the past you will have to raise the light as it can cause blindness ect if too close. IT IS VERY BRIGHT, NOTICABLE DIFFERENCE!hope this helps!

Question 2

What are the uvb output and heat production for this zoo med powersun lighting fixture compared to exo terra sunray 70w, 50w, or 35w?

Accepted Answer

The PowerSun HID kit is rated at 70W but the output is closer to a 100W UVB bulb at all the way down to 18”. Switched over my tortoises and bearded dragon to this fixture last year and noticed immediate change in their appearance and activity level. Plus it doesn’t die after 2 months.

Question 3

How much UVA is emitted by this light?

Accepted Answer

I just received mine. In comparison to the MyComfyPets 100watt 200 UVB bulb that I have in another setup: According to my reptizoo UV sensor cards, which are for approximate comparison only, this setup puts out about twice as much UV as the 100watt mercury bulb and twice as much visible light at much higher color temperature, it's almost too much really. It's very annoying in the evenings. The nice thing about this one is it has very predictable UVB output, good, uniformity and good instructions for getting it right based on your animal.  At 12 inches, it is comparable to full sun for UVB and visible light, but not heat (very low infrared output). It only gets the basking spot to about 89 deg at this distance unfortunately. It's not safe to put it any closer due to the high UV output, so this bulb can not be used alone if you need higher temps than 90deg, which you probably do if your pet needs this much UVB. This would be great if you want full UVB coverage for a larger cage, but you will definitely need an additional heat source if you have a bearded dragon. Given that this only uses 70watts, this may still be a more efficient option depending on how much extra heat you need. The mercury bulbs also have this problem and are therefore not an all in one solution as claimed.

Question 4

Does anybody know how quickly the uvb diminishes over time? I have heard that the claims of it lasting twice as long as Mercury vapor is not true

Accepted Answer

I’ve had two setups running for 15 months now and the UVB output has only dropped 10%. They were comparable to a 100W bulb at 18” when they were new.
