All the alternatives I’ve seen have one or more of the following problems: • Price [Metal Halide] • High minimum wattage [Metal Halide] • Poor white light output [LEDs, electro-luminesence] • Cannot run at low voltages, requires expensive or inefficient voltage converters [Metal Halide, fluorescence] • Wide angle and poor Lumens/m^2 require large optics.

[carbide, propane and other ‘flame’ lamps]. Most of us use red LED tail lights. I also have a flashing green electro-luminescent belt. These are both used as “be seen
