Ah cool you have the 250w hps luminaire and 400w luminaire retrofit lamps. It's too bad cmh never took off. I love the color quality and performance of cmh luminaires.

I think the biggest reason was cost. These would sell for $70 USd +/-. With the rather short lifespan, it didn't make since to the bean counters. (Had a customer back in the day who felt this way.)

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

Oh yeah I'd never pay full price for one of these either. But if everyone started using them the price would drop.

I believe the actual cmh lamps have a 24k hour life just like hps?

Unfortunately, these have been discontinued (probably at the time Philips Bath, NY plant was closed down).

The data I've seen shows that there lifespan to be about the same as a DX HPS.

The Philips MasterColor CMH lamps (the ones that operate on standard PSMH gear) are rated to 20000 hours but I've never seen any in use closely enough to tell if they really last that long. The way things are looking hear, a lot of HPS lamps (Sylvania ones specifically) aren't meeting their rated 24000HR lifespan. The utility company here uses Sylvania HPS lamps and quite a few I've seen are cyclers right out of the box! The Sun-Tech photocells they use aren't much better either. Quite a few dayburner photocells right of the box too. Apparently not all the linemen test the lights after making repairs. Most lighting repairs are done at night by the utility so they don't catch dayburners a lot of the time. Usually a dayburner will go unnoticed until the lamp burns out and someone reports it.

But as of right now, my utility only offers LEDs to municipalities that pitch in the cost, and only on a spot replacement basis. Other than that, they're all HPS. However, they offer municipalities the option to purchase ownership of existing luminaires and then buy their own LED luminaires and hire a contractor to install them. At that point the city or town pays the utility company for the estimated kWh usage of the luminaires and a small fee for pole space. Historically, the municipalities paid monthly kWh usage and an annual rental fee for each utility-owned luminaire. The rental fee ranged from $50 to $150 a year. The utility company is trying to get out of the lighting business here, as the existing infrastructure has been in use since the early 1990s and luminaires are failing at an accelerating rate. But still, they make a killing off each luminaire so I'm not sure why they want to give that up. I suppose they'd rather collect on the "free" money (the energy usage and pole space fees). As long as the grid is powered up their responsibility to the luminaires is done.
