Is anyone manufacturing a Luxeon circuit board and heatsink assembly that can retrofit existing cobrahead style light fixtures? If so where can I look at such a product? In my area of the U.S. the line voltage is 120 volts a.c. Some times 220 is used but not as common for street lighting.
Any recommendations to provide good CRI quality lighting with the benefits of long service life and reduced energy consumption is the step in the right direction, Thanks for the feedback.
