did you all remove the plastic light cover? Or is it thin enough to not filter out too much of the uvb?

I did not re,I've the cover. And I don't have the equipment to measure UV output, but I assumed that it was designed properly to not block the passage of UV rays.

I never tested it so I am assuming the UVB passed through since it is a thin plastic and I would have hoped the manufacture did test that. Also I felt it was safer to have a protective barrier between the water and the light tube just in case. UVB does pass though plastics and some glass but may be "diluted" or refracted and depending on the thickness and the clarity of the material it can be blocked completely. Also UVB does dissipate with distance so you need to read the details to ensure it is placed appropriately. Hope this helps....

I don't use mine for lizards but for supplement lighting on plants, but I don't think you will need to remove the covers when using for lizards. Zilla specially formulated the bulbs and my plants are native to the tops of mountains and need a lot of UVB to develop properly and they grow beautifully with this and my LED fixture which covers everything other than UVB.

Alex, I leave mine on to because it helps protect the lens. It also helps me learn to make adjustments with light. This weekend I'm planning to test full sun photography with and without it. I'll let you know my results.

It's not super clear but uv will get through. It is essentially bubble wrap. It warms the pool. But I did notice I need more Algaecide for control.

I'd say skip the lense. In order to get a more diffused light, I made a disk of lens tissue slightly larger than the included glass lens, placed it on the inside face of the glass and put the cover back on. This does dim the overall output a bit, but it's very bright, so the diffusion is worth it (for me). It's still painfully bright, do NOT look into these lights, you'll have a blind spot for 20 minutes!

The plastic is pretty thick. It might be too thick to have any light shine through.

Yes, it is better to take it out for the use you refer to, as it cuts light.Just have the normal UV - lens protecting filter on.

Hi Eric! The white will show through a bit of light, though the others keep the majority of the light hidden. A bit will peek through, though it will be a lot less than without the covers. As some customers have mentioned here, it's all a matter of preference and may depend on how much light you need. Apologies if that is a bit vague. If there's anything else, just let me know. I can be contacted directly via this link:

I would take out the filters from behind the UV lamp and then put the back on the unit. When you turn on the unit the UV violet color should show through the back fins of the case. If not then your UV light could be not working.

It seems to block light pretty well overall. Sometimes there is a little that creeps in on the bottom, but usually it is just a matter of pulling the mask down a little bit more so that it is sitting right. I can't promise perfection, but I haven't found anything better yet.

Yes, I once exposed a screen longer than the recommended time and it was extremely difficult to remove the part that should wash out. Instead of coming out with a forceful spray of water I had to scrub. I believe it's important to stick to the exact time listed for the light source you are using.

Another reviewer mentioned that there's a thin plastic protective coat over the lens that some people are not removing before using. Is this possibly your issue?

There is a little door on the side of the unit that opens up. You will see the light from the UV bulb shining through if it is on. (Read your manual!)

Did you remove the plastic protective sheet on the outside of the lens before you first used it?

Yes. Turn off all filters and just use this filter and uv light for two or three days. Amazing results.

Like you I didn't care much for the OEM hood. I use a thin UV filter with a soft rubber collapsible hood. Each his own but it works good for me.

I was thinking the same thing. I am thinking about buying a reptile light they make uvb

Not sure. I wasnt too concerned because my regular glasses have both UVA and UVB protection.
