Check UVB

No problem. Thanks a lot for your help.
I checked all three models you are talking about. They all give a stepped approximation to a sinewave at the output.

I think this will not be a problem for your UVB lamp.
But, I do not want your purchase to be in vain. I still think that ChatGPT gave you incorrect advice about checking for flickering at a frequency of 240 Hz.
Before you buy this UPS, I would like to ask you about the method of shooting flickering. I am very afraid that after buying the UPS you will see flickering again. I want to repeat your experiment myself on my Arkadia lamp.
I could not find such a shooting mode in my phone, I will try to find other phone models that are available to me, I will also check the capabilities of my SLR camera.

Hi, I sincerely very appreciate your concern to me and my dragon. Don't worry, I'm also searching is there any experience store I can test before really buying it, I'm also asking Arcadia in Messenger do they have any other advice to reduce or eliminate the flickering, at the same put my dragon under the lamp as much as possible (while he keeps running away himself) see any luck he can slowly adapt to it.

The camera mode I'm using to shoot all the videos is slow motion mode 240 FPS, the mode name is "slo-mo" in iPhone7. I also use another phone to shoot at 120 FPS it shows flickering too just not as serious as in 240 FPS.

It is sure that we can't fully trust ChatGPT.. But if not flickering, I can't figure out what else my dragon is scared of and made him keep hiding whenever UVB is on.

Hi just want to share here the reply I've gotten from Arcadia. They confirm the lamp ballast is at the speed that impossible to be seen by reptiles. The camera can see is because of the technology (I don't very understand the number part though). They also mention some dragons might need some times to get used to it.

It has been 8 days since we using the lamp. I think I can only continue let him trying, at the same time try to bring him out for sun bask every morning, see if he can slowly get used to this "healthy lifestyle"

I understood what they meant.
They said that their lamp flickers at a rate of 30 thousand per second. Your phone shoots at a rate of 240 frames per second.
But you see flickering on the video because of the strobe effect.
Let me give you an example. You probably noticed that on a video of a flying airplane or helicopter, it seems that their propellers are rotating very slowly, they can even freeze and it seems that they are not rotating.
This is the strobe effect that you observe when you shoot a video of your lamp. The lamp flickers very quickly (30,000 times per second), but on the video it seems that it flickers so slowly that the human eye can see it.

Thanks for your explanation, but I think I might need more time to study it as a college subject..😅

Arcadia says my tank is too low for 12% UVB, should I try the 6% and put my dragon directly under the lamp?

If you want my opinion, I think 6 percent is too low for a bearded dragon.
You said your distances are between 12 and 15 inches, that's a good distance for a 12 percent UVB lamp.
Are you still having problems with your dragon and lamp? Maybe there are improvements?

Hi sorry for throwing the question too fast, is okay I remain 12% and lift up the mesh so the lamp from his back is controlled within 13-14".. this should be okay right?

Yes actually he started to show improvement by being not so frightened under the lamp, also coming out more on himself in the morning today. I'm so sorry that I adjust his light again today he might need to adapt to it again.

Yes, that's fine. Anything within 12-15 inches will be fine.
If you're worried about the distance, you can add decor so your dragon can choose to go higher.

Aww your profile picture is precious ❤️‍🩹
Hey! I'm planning on ordering a 4x2x2 for my next beardie but I'm worried about lighting. I have a UVA and a UVB but they are small (the UVA just being a bulb and the UVB being 12 ish inches?) My house is drafty so I need a strong light that puts off quite a good amount of heat, any suggestions?
