Exley showed up to do a dive with me sporting a light that had been given to him by a manufacturer. I made him dive one of my Gavin lights. I hope that answers that part of the question. What we do now for ridiculous dives is use underwater connectors and extra slugs. The HID bulbs tend to not fail, and the others have a 50 hour life, so I guess if you were doing one hour dives and never changed your bulb, 1 in 50 dives would be in the dark. I change a halogen bulb every ten hours I keep a scorecard in the light canister ). The worst failure is having the inside wire of the cord break . That you have to watch closely, and if it looks to beat, change it out. The failure usually will be at the bulb end, rather than the canister end where you would expect it. Keeping your cord the correct length and not folding it up or wrapping it like the strokes do prevents a lot of this. The switch should go for years unless it gets wet or is a cheap switch. ----- Original Message ----- From: Jeffrey Bucovetsky <jeffb@de*.co*> To: <techdiver@aquanaut.com> Sent: Thursday, September 28, 2000 11:10 AM Subject: Light Failures > Hello list. > > I have been a lurker here for quite some time, and appreciate all the > constructive posts.
