Why not more POWR/DOOR or PowerPad fixtures « on: June 22, 2016, 04:40:16 PM » Author: M250R201SA
Why don't utilities use more M250A2 POWR/DOOR instead of the M250R2?  Wouldn't it be easier to R&R POWR/DOOR luminaires instead of R&R M250R2, M400R3, etc.  Personally, I would us eht M250A2 and M400A3 due to their simplicity to work on.  Price?

It's because single door fixtures are cheaper.

So, the single door fixtures are cheaper, and it costs less time to just remove the bad fixture, and replace it with a new one. 

Probably why the Durastar series didn't take off.  It is pretty time consuming compared to installing an M250R2

No, it tkes less tim to swap out a gear tray (or door)

But as often things go, somebody specifies the fixtures only based on things "in the scope of his job" under pressure to keep costs down on those things only. So he may well choose a fixture that is 5% cheaper cause that is what he is obligated to do, but would involve 20% higher maintenance costs (and its still a fairly good case) but that are some other department's expenses..

Around here, the reason they never took off is because the replacement Power/door ballast modules don't cost that much less than never fixtures, and in the eyes of the electric company, street lights depreciate to little value just like how a new car looses half its value the second it's driven off the lot. Once the fixture is installed and used, 10 years later, it's only worth its price in scrap, so they replace it. Who's to say a component won't break down the line and rack up the maintenance expenses? By installing a brand-new light, they can rest safe that the entire fixture is under warranty. A twisted way of thinking, but it all comes down to cost in the end.

The degree of standardization has a lot to do with it also.  I've noticed Powr/Doors to be most popular with utilities or entities that have fairly standardized lights, so there's a good chance that a replacement door will fit a good majority of fixtures the repairman could be faced with.  Areas with little to no standardization, especially among their larger fixtures, I've almost never seen Powr/Door fixtures.  The repairman could go out and find almost anything up on the pole, so a complete replacement fixture would be more practical.

We have a huge variety here and we used Powr/Doors. But they never replaced the doors on them. when the fixture failed or it was time for HPS, new fixtures were installed.  We had used M-250As and M-250A2 FCOs. The M-250A2 FCOs all had dual-wattage 100/175W MV ballasts. The fixtures had 240V reactor ballasts with a 120V PC socket. The M-250As were also 240V with 120V PC but they were 100 or 175W single wattage.
