Lighting for impact swing camera high fps

Great info! Which dimmer switch are you using?

[Carl Johnson]

Great article! Thank you!! Snoots! I have to look into added those to my current set-up.

how are you using thesse?

Ron you are a gem sir. Thanks for all the help!

I wrote up an article today that may help some folks: https://gunghogolf.com/articles/indo...video-lighting

That certainly might work - would have to test to ensure the DC Converter's drivers did not cause any flickering. But, some landscaping lights are not cheap so is there any benefit using a landscape light versus a track light with viable drivers?? Trackman seems to suggest Jett04 lights which are indoor track lights. I may try a few of these but they will not work with my Juno tracks so not as easy as just plugging a few in to try - I would have to install all new tracks to try the Jett lights.

What about using 12w led landscape lights with an a/c to DC converter?

[Carl Johnson]

The LED driver is definitely key. Cheaper LED drivers will flicker like heck! Seems that some newer LEDs fixtures are using two DC drivers in the fixture so it must be 120v to the fixture then converts to DC for the light output - not even sure what the 2nd DC driver is for? I am still putting my SIM back together - had concrete floor cut and having carpet re-installed. I will try to get some video clips done this weekend or early next week. From seeing pathfindr's video and clearly no flicker that I can see - makes me pretty upset about my LED fixtures - my flicker (when no sunlight coming in the room) is pretty bad!

Picture quality is really good actually and no flicker! Fairly dark though - would love to see a little more lumens around you.

So I did meet with a lighting manufacturer in nj basically said any led light could be flicker free with correct drover in it. Picking up the lights Monday. I am also trying to get cost on some spotlight lights they make with the driver they recommend. Believe it could definitely be something reasonable enough for all of us. Upgraded driver which was told like 50 a light has correct frequency for anything 500fps and lower. Pathfindr your shadows come from where you have lights up on ceiling. I was told need 3 sets of 2 1200 lumens each light and an 20 or 30 degree optic to light up 9ft circle. Makes that blacked out room with clear image of golfer and club. Was told behind front of golfer, back of golfer and down the line for each golfer. Will get driver info for everyone and will show pictures of lights to see what everyone thinks

I was using ELP cameras 720P at 120 fps. I have since upgraded to IDS 3060 using 150fps. See this sample video I just uploaded https://www.youtube.com/watch?v=AJNzDFoRx6o The description section has more info on my setup.

pathfindr - what cameras are you using with those LED lights? And, what frame rates are they set to? Thank you!!

[pathfindr]

One downside of adding more lights is that too much light may make the room too bright and wash out the projector screen image. I ended up getting cameras with a large low-light image sensor that works great in indoor low lighting.

Look for LED lights with a constant current driver such as this one https://www.amazon.com/gp/product/B07XG37F14 They won't cause flickering even at high frame rate.

Also, for camera frame rate. The advertised frame rate is at maximum resolution. For example, for IDS 3060, the max frame rate is 166 fps but that is at the max resolution of 1936 x 1216. If you lower the resolution, you can achieve much higher frame rate. I have no problem recording at 300+ fps if I adjust the resolution. Keep in mind that you will rarely record at the maximum resolution because you will max out the USB port (5Gbps) and start dropping frames. I usually record only at 1440 x 800 or even at 720P at 150fps with my IDS 3060.

I use 2 x 300W LED. These lights work great without flickering even at high speed frame rate. They have a constant current LED driver which doesn't cycle on/off like typical LED lights. 2 X 300W LED Light https://www.amazon.com/gp/product/B07XG37F14
