Lighting for impact swing camera high fps

[LeftyLeff52]

Looking to start discussion on which lighting people have tried with high fps cameras to take away blur and have clear image of golf swing. About to pull trigger on 2 camera setup and need answers on how many lights is required for clear video

[FanSheets]

how are you using thesse?

Ordered Satco 33W PAR38 3000K High Lumen LED from BulbAmerica.com, as recommended by Ron (GunghoGolf) on Thursday and received them this morning (Saturday). They are very bright (3000 Lumens) I did a quick test using my iphone in slowmo video and there was no flickering at all. They have 40 degree narrow beam angle which is nice. I'm looking to move my sim setup from my garage to inside the house and have been buying and testing various less-industrial looking non-flickering lights than what I currently have. During my testing, I did find some recessed LED lights that don't have flickering at high frame rate (such as this one https://www.amazon.com/gp/product/B082XLKTT4 ) but most of them have pretty wide bean angle like 110 or 120 degree. Really appreciate Ron's info.

[pathfindr]

I also ordered the 5000K version which has a more white/cooler color. https://www.bulbamerica.com/products...-base-120-volt They also have a 4000K version https://www.bulbamerica.com/products...-base-120-volt

Also, I notice that Lowes has H type tracks that are 50% cheaper than WAC brand on Amazon. (4-feet track is $14 vs $28 WAC on Amazon) I don't know if the quality is the same or not but thought I would pass along this info.

Found a possible simple lighting option - therapy lights. Have any of you guys tried it? 10k lux, no flicker, small size, plug. Not sure if they actually mean 10k lumens, some answers say it's lumens, I saw a youtube video where they messaged the company and said it was only like 900 lumens. Reading how it's super bright makes me think it's lumens - I do have a 15k lumen light (apparently - it's a cheap light that flickers like crazy) and it is blinding.

"No flicker" in that context means no flicker visible to the eye - different from truly no flicker under slow-mo video capture. Also, it would be very hard to snoot one of those panels to keep light off the screen - panels give a broad light pattern, the opposite of what you want for swing video use. Doubt that panel is any brighter than a single Satco 3K lumen bulb listed in my article at https://gunghogolf.com/articles/indo...video-lighting.

[stunted]

It's possible it's not flicker because it uses DC power. But it doesn't seem strong enough, using a lumen/lux calculator it seems to fall well short...but not sure if I put in the data correctly. Me personally I'm going for something that can capture the club and shaft without blur, so would need at least 20k lumens I think.

[GungHoGolf]

Yes, we use at least 6 of the true 3,000 lumen bulbs to stop the club without blur. Takes way more light than you think, even with fast lenses.

[stunted]

Is this one confirmed to have a constant current LED driver? It's the same company as the one pathfindr used https://www.amazon.com/gp/product/B07XG37F14

If he used 2 of them, that means his room has 60k lumens?

I have a 15k lumen light, I think it is usable down to around -9 exposure for the OV4689...that is if it didn't flicker.

[Toothboy]

I bought these and mounted the Uneekor swing optic cameras directly onto the same tripods that the lights are mounted on. Plenty bright enough and zero flicker/blur

I sent you a dm as well but are you still happy with this setup? Do you have any pics or video of the results that you can post? I'm trying to figure out lighting for my setup now and these seems like it would be easiest if it works.

25k+ lumens, no flicker

stunted Did you ever get a chance to test those 2 bulbs? I have a garage setup and I’m not concerned about washing out the projector. All I really need is enough light to record in 240fps (without flicker preferably) when it’s too cold to go outside. I have an old Casio that I use when I go outside and my phone will also record in 240, but both require way more light than what I have currently. Just trying to find something plug and play if that even exists.

[pathfindr]

I use these lights in my garage setup. https://www.amazon.com/gp/product/B07XG37F14 No flickering at 240fps. Here is a sample video. More details in the video description section on my setup https://www.youtube.com/watch?v=AJNzDFoRx6o

pathfindr - Is your garage a 20x20? How did you place each fixture? Where is your hitting location in relationship to the light placement? Do you have a drawing of the layout? Might be easier to just take a picture of your ceiling.

[pathfindr]

I'm in the process of building a new setup inside the house and don't have the garage setup anymore. For my garage setup, I have an oversized 26 x 24 garage with a 10 ft ceiling height but the hitting zone is about 12 x 18 ft. (I have a 10 ft wide Sportscreen with side curtains on Ikea tracks). The lights are directly above me and the hitting area. The lights come with metal hanging chain and brackets. I use heavy duty velcro hanging straps (https://www.homedepot.com/p/Husky-24...9-TH/312387462 ) to hang the lights to garage rafters directly so that I can move and adjust the position of lights easily. Take a look at this old video which shows the lights above the hitting area. https://www.youtube.com/watch?v=WDazmplL2YY
I was using black plastic roof vents to prevent the lights from washing out the projector image.

yea I have the 2nd link, and you just screw it right into any light socket. it is incredibly bright. it's 75% as bright as pathfindr's link as reference, so it'll work well.

pathfindr I ended up doing 2 of the 155W Hykolity lights. 40000+ lumens (2 x 20000+) is very very bright. Doubling that like your setup would be like the sun, and I can't imagine how bright that actually is. I don't get any flickering at 240FPS which is what I was looking for. I did add a 0-10V dimmer as well which is nice when you don't want to be in high speed video capture (or x-ray machine, lol) mode. I need to do some testing with my Casio camera that allows me to manually change the shutter speed so I can find the right combination of settings to remove the club blur indoors. I'm confident it'll do the job. I'm still trying to wrap my head around how you positioned the light shields to prevent wash out.

Thank you for the follow-up stunted !

[pathfindr]

Just an FYI - Avoid Lutron Toggler dimmer switch. Using a on/off switch with Satco LED, I'm not getting any flickering. When I used a Lutron Toggler dimmer switch, I was getting flickering. This is the Lutron switch https://www.homedepot.com/p/Lutron-T...H-WH/202746671

[EG$]

pathfindr - That was actually the dimmer I had in the space to control the standard bulbs prior to adding the Hykolity lights, and you're right, its no good for anything on a commercial level. It worked fine for strictly On/Off, but was unusable for dimming in any capacity. The Hykolity lights and most commercial grade LED drivers require 0-10V dimmers which are very difficult if not impossible to find in the big box hardware stores. I don't think they stock them normally.

Lutron does make a solid solution and I ended up going with that and it works great. It doesn't dim the lights enough to prevent washout but I was after enough light to capture video. I turn off these lights when using the projector.

This is the part list I used for dimming:
Pow Pak Dimming Module : RMJ-5T-DV-B
Pico Wireless Remote: PJ2-2BRL-GWH-L01
Wall Plate Adapter: PICO-WBX-ADAPT

My setup is working flawlessly. No flickering, and now no blur after finding the right shutter configuration on the camera.

Someone asked me about my lighting setup. So I thought I would post some info here.

I basically followed Gungho Golf's recommended setup https://gunghogolf.com/articles/indo...video-lighting posted from Ron. For the light, I use 1 8-ft track from Lowes https://www.lowes.com/pd/Lithonia-Li...ack/1000400947 directly above my head perpendicular to the screen (See photo). I have 6 lights. I was also considering lights facing the golfer but didn't end up needing them. I didn't want to have light directly in my face. I also use EV foam sheet as light snoot to block off the light. https://www.amazon.com/gp/product/B084P8P8QR I use a binder clip to secure the foam to the light. See photo. For the dimmer, I found an older style dimmer that actually works without flickering. It's not designed for LED but it actually works better than those dimmers designed for LED. The model number Leviton Almond Decora Illuminated Slide Dimmer Switch Preset 3-Way 600W 6633-PLA. I got them on ebay. The listing is no longer there but I think this is similar. https://www.ebay.com/itm/234612712862

[pathfindr]

My track is about 40 inches left of the driver tee. The lights are directly above my head. I have a 10ft ceiling and fixture is about 10 inches from the ceiling. Unless you are very tall and have a very vertical driver swing, I'm 5 ft 10 and have not had any issue with the driver hitting the lights. I don't have any issues with shadows affecting putting. Best way is to test the different locations and see what works best for you setup. There is an adapter/cord kit that you can buy that allows you to power the track and move the track more easily. https://www.amazon.com/gp/product/B001PIKORA It's basically a 15-ft long power cord that you can connect to the end of the track and the other end can be plugged into any outlet.

Thank-you for the quick reply. Full disclosure I recently had rotator cuff surgery and unfortunately can't swing a club. It appears you basically followed Ron @ GungHo's recommendation but with only one track. I understand about the driver not hitting the fixtures. Since I can't swing a club right now to test out, I'm having trouble envisioning if an iron could hit the fixtures. In your opinion do you think there is any chance? I'm 5'11" but do have some tall players i.e. 6'4".. Just curious as to what you might think. Much appreciated!

[pathfindr]

Irons are shorter than a driver and should be even less an issue. You can always move the track to the other side, assuming you don't have lefties. It's not difficult to move the track, especially if you use the adapter/cord kit. You can also move the lights along the track if any of the lights are in the way.

[pathfindr]

Since someone DM me and asked about my current light layout, so I thought I would post it here as well. FWIW My current light layout with 6 lights. I added a second track and use two adapters and a home made power cord to provide power to the 2nd track. https://www.amazon.com/gp/product/B0071C7652

[rob.burge]

Hi, do you have any blur on you dtl camera with your current set up on the downswing? Thanks for sharing.

[pathfindr]

No, I'm using Swing optix cameras. But I have also tested a 100fps camera. As long as you keep the shutter speed high (low exposure time) with sufficient light, you should be able to get video without any motion blur.
