Weird HPS lamp behavior « on: January 12, 2023, 08:18:52 PM » Author: Burrito
There is this General Electric M400R2 (250 watt HPS) fixture that started cycling a few months back. Weird thing is, sometimes the lamp not illuminate for hours at all then suddenly start cycling. It can sometimes hold the arc for long periods of time. Anyone know what causes this?

LED street lights are bad. Some look good though. HID is better.
Please, watch out for the future. It's not looking good.

I've seen a behavior like this. HPS lamps that begins to cycles, initially cycle only seldom, and as the lamp gets older, it cycles more frequently until it cycles continuously. Also, when the lamp is turned on, there is a period that it won't cycle for several mins.

Anti-cycling ignitor could cause this?

He don't wording well. He means that the HPS lamp inside the GE M400R2 lights for hours than suddenly cycles. Anti-cycling ignitors aren't common in the US.

AngryHorse talked about anti-cycle ignitors, which are ignitors that stop working after few cycles, or not cycles at all, if they detects that the lamp is about to extinguish like this: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-210767
