Its common for OVX to have premature cycling....in 150 watts and up.....same goes for other Cooper fixtures, due to reflector design......we have lots of OVX in state of MD.......I've noticed highways get group relamped so its less common for them to cycle...and they work on them often anyway....but traffic light interscetions on the other hand....gets cyclers....often!

Do the Larger Coopers such as the OVY/OVF,OV-25 Cycle?

Well any lamp will cycle at its EOL but not as early as the smaller Coopers

Apparently the Design of Cooper Reflectors shines Excess IR Radiation Back at the lamps Arctube...which of course would make it run a tad Hotter than Normal which could make it Cycle Earlier....i think thats it...and thats my Theory.

Lamps always like to cycle in these, including some of those rebadged AE 125 Series ones too.

Theres a 15KM stretch of 400 watt OVXs here, they where all relamped (after me harassing the city for about two months) back in March '10 and many are already starting to cycle I wonder how long until I'll have to start harassing them again to do a group relamping

Here the state waits for the majority of the lamps to be dead before doing a replamping. By then most of the starters and some ballasts are dead from operating expired lamps, so they end up replaceing the fixtures instead. RIDOT is too lazy to fix the starters.

The Massachusetts DOT ain't any better, there have lights that have been out on the interstates for over 10 years! now thats lazy

On I-95 in norther Mass. There are M-400A2s and highmasts for miles. You probably know what I am talikign about Tony. Lot burnt out and not working.

Last night, it was out. Today I went to fix it and it is more than a bulb or igniter. I took it down and may end up putting a GE M400R2 FCO in its place.

Cooper Cuality.

Kooper's Kooky Kwality Kontrol

Now they are talking about getting Cooper LEDs to replace the HPS.

hopefully the LEDs outlast this OVX lol.
