Current fluorescent lamps are great for lighting large areas
using very few Watts; however, LEDs are far more efficient at
producing light and have less of an impact upon the environment
considering there is no mercury within them. [Andrew] sent in
his team’s LED florescent bulb. The first revision utilized 87
LEDs, but to increase output the second revision uses 210. The
assembly can’t actually be placed in current fluorescent lamp
ballasts and must use a 12 volt 1 amp power supply, but perhaps
future versions will correct for this. Another problem is the
relatively small viewing angle, and while there is a diffuser,
we’re wondering if they have any other ideas to spread the light
and adjust for the color temperature without reducing output? We
wonder how it compares to some of the commercially available LED
florescent lamps.
