LPS is pick'n up speed at my dads building, I have to remove 4 hps 100 wall packs replace 2 with 2 90w LPS and one 18w and the LEDs stopped working because there was a short ALL led street lights are trash, The clear and effective street light is LPS
Your dad's building will be easy to spot at night, just look for the golden LPS light. Too bad the LEDs stopped working. I love the crisp light from LEDs but the technology just hasn't developed enough to be nice and tough like HID, which is a proven technology. I've seen indoor LEDs and they're great but I just dn't think LEDs are fit to replace HID lights. Like you've said, LPS is way more efficient, albeit low CRI. LED is actually about as bright as PSMH or CMH, which are both close to HPS in efficiency (I'd argue that CMH is more efficient than HPS because the high CRI makes CMH look brighter than HPS even though HPS is rated for more lumens).
Are these signals operating? Or are they just for display? That would be realy cool if these all worked.
