Claim Text:
1. A system comprising: a housing having a first end and a second end; a first set of light emitting diodes; a channel coupled to said first set of light emitting diodes, said channel comprising a surface to be coupled to said first set of light emitting diodes, said channel adapted to thermally insulate wiring of said system from heat generated via said first set of light emitting diodes, said channel adapted to resist bending when forces are applied to said system; a threaded center shaft, said center shaft adapted to fit through said channel and extends beyond said ends of said housing; said center shaft adapted to resist bending when forces are applied to said system; said center shaft adapted to isolate end lifting forces to said system when a chain or cable is coupled to said center shaft; a first stopper, said first stopper adapted to substantially surround a first threaded end of said center shaft, said first stopper adapted to plug said first end of said housing and resist penetration of water into said housing; a second stopper, said second stopper adapted to substantially surround a second threaded end of said center shaft, said second stopper adapted to plug said second end of said housing and resist penetration of water into said housing, said channel adapted to brace said first stopper and said second stopper and to resist motion of said stoppers when said system is under water; and a washer, said washer having a same shape as a cross section of said housing and placed over an end of said center shaft, said washer coupled to said system via a threaded nut coupled to said first threaded end of said center shaft; a protective end cap, said protective end cap adapted to resist penetration of water into said housing and shield ends of said system when said system comes into contact with another object.
