Permanent lights are typically powered with 115 volt house current.
Placed on poles at the end of a dock or pier, the least expensive lights for outdoor use are security or flood lights using a mercury vapor, high pressure sodium vapor, metal-halide discharge or fluorescent bulb.
They cost $ 25 to $ 100.
While lower cost 115 V AC outdoor flood lights using standard tungsten ( incandescent ) or tungsten-halogen ( quartz ) bulbs can also be effective fish attractors, they are energy inefficient.
It takes about five 100 watt tungsten lamps to deliver the light equivalent of one security lamp.
Security lights are readily available from most hardware or farm supply stores.
The fixture includes a photocell controller for automatic dusk-to-dawn operation and comes complete with an appropriate bulb.
These lights are very bright ( 6-8 thousand lumens ), efficient in converting electricity to light ( operated daily for 8 hours, electrical supply costs $ 40 –$ 100 per year ), have long bulb lifetimes ( 24, 000 hours ) and stand up well to outside weather conditions.
When used as a fishing light, light output can be redirected toward the water by installing a 5 ” X 10 ” piece of aluminum flashing or heavy foil bent into a half circle and placed next to the lamp's circular acrylic lens.
