Ah you got another. yeah LEDs seem to be better off in climate-controlled areas. they work beautifully for emergency lights. The batteries can last well over 90 minutes and you get a lot more light from them too. I don't get why emergency heads sold today are still halogen. LED exit signs as we all know are terrible too. LED traffic signals are good on the road too since they use less energy and last longer but for my personal collection I prefer incandescent.
LEDs can work for street lighting but right now the distribution is terrible, they look very ugly, and the fixtures are not even outlasting MH lamps even though they're supposed to last 20+ years before requiring maintenance. If you need lamps to last 20+ years or even 40+ years, MV is the way to go. There's a good number of 1960s mercs still around and they're fairly bright. After the 1960s companies started intentionally degrading MV lamps because the lamps were lasting "too long".
Brian, can you post a pic of one of these installed on your dad's building?
Yes, the LED emergency lights are do'n very good they last 5h on back up and give 3300lm per big unit and the LED 3Ms are fine. I will put the LPS stuff up in the fall and, I will show you how good they are
