|This is my first attempt to make a lamp for use under water. It is a normal halogeen lamp, with an aluminium tube which is filled with silicon kit. Unfortunately the lamp itself is not waterproof..... There is a gap in the glue, which holds the front glas.|
|This is my second attempt is with normal plastic
outlet pipe. In the bottom I placed a gland for the cable. (FarnellInOne.com)
I tested it in a buckle of water for more than 5 hours, switching it on and off and on and off. It didn't give a drip! Joepie!!
