NOTE: TJB-INC did a 9 month test using LED lamps from 8 manufacturers to see which product would hold up the best over time. The LED lamps were put into our Paver, Retaining Wall, Deck & Dock Kerr lighting fixtures in our outdoor displays. They were subjected to the same conditions you would have at your location.  We quickly found that you get what you pay for.  Within the first 2 months, several of the LED's stop working.  At 6 months, several more began to fail.  At the end of the 9 months, one brand was head and shoulders above the rest.  The LED lamps from Dauer Lampen.  Their LED's were as good as the day they were installed.  They also come with a full 5 year warranty, not 90 days to 2 years or pro-rated like the other manufacturers.  Because the LED's do not produce the heat the standard bulbs do, the lenses on the light fixtures will not need replacement as often due to the discolorization from the heat given off by standard bulbs.
