Which Spotlight bulbs don't cause banding with the silent shutter?

[Hindy]

Hi,

I have an Canon EOS R8 camera. A while back, I wrote a post asking where to find regular flicker-free light bulbs. I ended up finding several options:

But I am having a really hard time finding flicker-free BR40 spotlights bulbs for home use. 

I tried spotlights bulbs from Lowes, Ace, Amazon, Philips, Sylvania, Cree, Ecosmart, Luxrite, Sunco, & Alzo Digital but all of them flickered. 

If anyone knows of a genuinely flicker-free spotlight bulb, I would really appreciate it if you can please post where to buy one. 

Thank you very much!

Hi,

I tested tons of bulbs & found 3 spotlights that don't show banding until 1,000 of a second shutter speed. If you look through images taken at different shutter speeds quickly, you can see slight variations in brightness, but it's not noticeable on a single image. The vignetting you see in the picture is because it's a PAR38 bulb- which means it's a very focused beam of light.

I edited this post twice; because when I first tested the bulbs, I pointed the camera straight at the bulbs, and got "no flicker found". But for the 250 watt bulb, I later tested again at the side on a blank wall, and got "found 120hz flicker". I already returned the other 2 bulbs so I can't test them again.

Update: I bought Option 2 again- Color Selectable 90 watt bulb- and my camera says, "No flicker found", but I do see banding at the fastest 2 shutter speeds- 8,000 of a second and 16,000 of a second. But one thing is for sure, I did not see banding at 1,000 of a second shutter speed.

I ended up putting in the 250 watt spotlights (because the extra watts were needed) and I will test it for a month. 

If anyone has any of these and can comment, please do. Thank you.
