Re: [PSUBS-MAILIST] Under water lighting
well I designed the enclosures for the lights on lake diver that can except
many types of bulbs.generally car headlamps (round)
we tested flood type bulbs and straightshooting bulbs and found that the
flood bulbs worked much better. As far as halogens well
we found that the higher the candle power the better If any one is
interested in this enclosure design let me know id be more than happy to
share it
heck i'll build them for ya if you'd like they have been tested to 600 ft
