They are replacing 200w HPS lights around here with these. I really don't like them, the light quality is horrible and they only light a small patch underneath compared to the large area that the HPS lit.
RIDOT used these LeoTek LEDs to replace all their lighting (133W LED replacing 250W HPS and 280W LED replacing 400W HPS) and the lighting from them is pretty good but like 1/4 of RIDOT's freeway lighting has faults so the lights don't work. But the ones that DO work perform just as well as the FCO HPS they replaced. They fall a little short of drop lens HPS but make up for it with the color. We'll see how they're doing 10 years from now though...
