Underwater lights for photos
« on: January 10, 2020, 12:36:00 pm »
Having sorted myself a nice bright light for photos I'm wondering what people are using for underwater lights for photos? (as in putting the light in the water to light a streamway or lake while you take a photo above it)

This also loos like it might be effective - and it's cheap enough for a punt:

Those ‘18000’ lumen ones on amazon are good value and take standard 18650 cells. I’ve seen them used for underwater cave & wreck photogrammetry and they do the job. Very bright, similar to £1000+ video lights, but £50. Not 100% reliable. I think some failed out of a batch of 6 or 8. They are not suitable for use out of the water. Insufficient heat sink and get way too hot.

Thanks! I'll have a look and see what I can get. Though I'm wondering if it would worth spending slightly more and getting something that I can use for other things too.

I’ve used a mini q40 with a custom duo insert on occasions and it’s done the job, probably 50 all in..

I've got three of the three LED ones like this and they are adequate video lights.

Ive got 2 of the CD-SF3 'diving light' from http://www.customduo.co.uk/Caving-Torches/. Ive taken them to 20m and they were fine so should be good for your purpose and they take 18650's which most cavers have already.
