I just picked up a pair of Intova Galaxy's and upon charging and lighting them up to do a full battery drain test I noticed that while on the high setting the lights will occasionally (maybe once every minute or two) drop in intensity for about 30 seconds and then power back up to full. At first I thought it was just one light, but after troubleshooting more I've seen both do it a number of times.
Has anyone else experienced this? Is it something that is solved when the lights are submerged vs. above water? Is it just the lights trying to keep from overheating?
Any thoughts or previous experiences with this would be tremendously helpful.
