Are modern HPS lamps non cycling by default? « on: September 24, 2020, 08:55:29 PM » Author: Lightingguy1994
Hi, just curious if the recent made (within last 10 years) HPS lamps such as the Philips Ceramalux are designed by default to be non cycling? How about the Philips Ceramalux Alto?

I know that there are some ballasts out there that are anti-cycling, but as for bulbs themselves?  I don't think so.  But I suppose it is possible.. some sort of relay or resister built in to not allow power to the arc tube after 1 failed attempt and then gets reset when power to the ballast goes off via timer or photocell.

The more you hate the LED movement, the stronger it becomes.

I'm referring to the lamps that turn MV colour at EOL. I know philips at one point marketed their line of non cyclers as having that feature so that EOL lamps can be easily spotted. Some digging around on here and elsewhere had some mumblings that the recent lamps had this feature built in. I just want to either find or eventually end up with a mv burning HPS lamp to get that nice mercury colour in HPS only fixtures

I recently came across streetlighting specs for the City of Columbus and in it it stated that "HPS lamps are to be of the non-cycling type "  GE lists non-cycling lamps in their catalog , the ordering code ends with /NC

I dont think the "default" model to be the noncycling one. The noncycling features comes at a cost of other performance aspects, which are often preffered (efficacy, mercury content, the purchase cost even when the last is very relative).

I guess I'll just have to hope that one of my lamps has low sodium in it, I do have a 35w Philips that stays a peach colour so I got some hope. I believe I have a USA brand 50w one also that does

Is there a way to tell when a sodium bulb is the unsaturated type?

Quote from: Lightingguy1994 on October 08, 2020, 12:12:28 PM Is there a way to tell when a sodium bulb is the unsaturated type? Response of the arc voltage on the arc temperature variation. Saturated vapor lamps increase their voltage when you warm up the arctube more (by increasing the current,...) Unsaturated vapor lamps maintain the voltage rather constant.

Also: Unsaturated HPS lamp runs up mercury color all the way to full output, similar to MH lamps, without reaching SOX color.
