Great job on the video, which spotlights and LEDs are those, and can you provide a link?

Thanks

Jerry 713, adding to the info in your provided link; I worked enforcement in a boat for several years. Your link alluded to vessels running at night with docking lamps on. I found that many pontoon boaters did exactly that. Not only does that destroy other boaters’ night vision, as your article stated, and temporarily destroy the operator of the offender’s vessel’s night vision when they are first turned off, as the article also stated. It also limits the effective area the offending operator can see while they are on. I stopped numerous pontooners at night running docking lamps and tried to educate them. I told them that while they could see greater detail at short range with those docking lamps on, they were unable to see anything outside that narrow aura of light. Most were receptive. Some weren’t; they got to explain their superior knowledge to a judge. But I received quite a few followup calls from folks who told me that they tried running without docking lamps at night, and were amazed at how much better they could see without them.

Never have been able to watch the video. Is it in some "new" format?

Scratch that, works on my phone now, just not the work PC.
