Mercury in-your-fish light If you wondered what happened to all the leftover Regent 175w mercury yard lights, perhaps here is the answer. Here you see the Regent lamp, photocontrol, a home made ballast box with GFCI cord and watertight socket - something that could be built for less than $75 in parts if purchased at retail prices. But these lights sell for $250 and more! Notice the lamp is not enclosed.

What so the lamp is exposed in the water, how does that work
TiCoune66   [Feb 16, 2010 at 01:08 AM]
Of course, you put the lamp in the water BEFORE lighting it up, and not the opposite! Otherwise, the thermal shock will make it blow, BOOM!
Form109   [Feb 16, 2010 at 05:20 AM]
isnt the Borosilicate Glass very much Resistant to Thermal shock?...if your using this at Deep Depths id be more concerned with the Pressure from the Water making the lamp Implode.
Sailormoon_01_uk   [Feb 16, 2010 at 08:01 AM]
Any Lamp would explode due to sudden Temperature changes or cold water hitting a hot lamp, hard Glass lamps can be safely lit underwater from cold and in watertight lampsockets, they can withstand changes in water Pressure too.

I have a 1940/50s Osram GEC Special Diving Lamp which was used by the Royal Navy, the lamp has a 1mm thick glass bulb it is designed to operate with direct contact with the water, and withstand up to 1200ft depth which is about 600 pounds per Square inch of water pressure.

All the Best

I dont know, the whole thing seems a little fishy to me Laughing Laughing

I am not eating any fish out of that lake! id be worried some BIG fish would see the light and eat it.
Form109   [Mar 13, 2010 at 08:06 PM]
id like to see how Bright that 175 Watt Merc looks underwater.....orrrr a 1000 Watt MH!
joe_347V   [Mar 14, 2010 at 08:29 PM]
What about using a 1000W HPS underwater Smile
Form109   [Mar 14, 2010 at 11:00 PM]
Yeah way to kill the fish with its ugly Color. Smile
streetlight98   [Apr 23, 2011 at 04:13 PM]
Oh god. Poisoned fish. Shocked
gailgrove   [Jun 21, 2011 at 04:31 PM]
I've found a dual 400 watt HPS version of this Shocked I wonder what HPS cycling underwater would look like Surprised
joe_347V   [Jun 21, 2011 at 04:58 PM]
A underwater beacon Laughing
streetlight98   [Jun 21, 2011 at 09:38 PM]
Eh, doesn't seem like a "Bright" idea. Laughing Confused
Tmcdllr   [Jun 22, 2011 at 02:05 AM]
Hmm, this idea isn't "washed up" yet?
gailgrove   [Jun 22, 2011 at 02:10 AM]
I like the idea of underwater lighting, it would look cool if nothing else.
Tmcdllr   [Jun 22, 2011 at 02:41 AM]
I checked this out awhile ago and on their site there are some neat pics of it lit underwater.
GEsoftwhite100watts   [Apr 11, 2013 at 01:25 AM]
LOL! Laughing I wonder how well this really works in real life?
streetlight98   [Apr 11, 2013 at 02:02 AM]
as long as you put the lamp in the water BEFORE turning it on you should be good (and make sure you don't hit the lamp on anything hard since that won't be good either lol). otherwise thermal shock will destroy the outer glass. If someone used a metal halide lamp on this i wonder what an underwater EOL eplosion would look like... Shocked definetly not good for the marine life!
GEsoftwhite100watts   [Apr 11, 2013 at 02:04 AM]
Yeah even if the lamp restruck I imagine it would be interesting!
HPSM250R2   [Mar 28, 2019 at 11:51 AM]
Yeah this company is based here in Port Charlotte, Florida. I just checked out the website www.underwaterfishlight.com. They're still making these. I wonder where they are getting the 175 watt MV ballasts? Unless they're using MH ballasts.
