EYE Sunlux Ultra Ace NH360FCE 360w high pressure sodium retrofit lamp for 400w MH or MV fixtures

This retrofit lamp is designed to retrofit 400w metal halide or mercury vapor bulbs, and uses only 360watts.
Thanks to ‪@worldwidehidcollectorusa-fkt‬ for telling me about the difference between the LC and CE series lamps!

That is a really beautiful lamp you have here!!!
I have an Iwasaki Clean Ace 400W metal halide retrofit lamp for mercury vapor ballasts, but it is only compatible with HX autotransformer ballasts and series choke ballasts much like Sylvania’s Unalux lamps, but it emits a very beautiful 90+ CRI 6500K glow. Fortunately, I have the proper 400W H33 mercury vapor HX autotransformer ballast for it. On the inside of that lamp, it utilizes an internal glowbottle starter much like what you see in preheat fluorescent luminaires.
Additionally, Iwasaki also made some FEC ignitor 360W ceramic metal halide lamps that have internal FEC ignitors that can be retrofitted into 400W M59 probe start metal halide CWA ballasts and 400W H33 mercury vapor CWA ballasts for the North American market. That lamp is known by the part number “CMP360/BUD/840/I”.

Very cool. I really want one of those 360w CMH retrofits. Is the light output similar to the 360w HPS retrofit?

[@worldwidehidcollectorusa-fkt]

@@HIDLad001 According to Iwasaki North America’s catalogs, it mentions the NH360FCE high pressure sodium lamp having an initial lumen output of 43,000 lumens and a mean lumen output of 38,700 lumens. Additionally, the ceramic metal halide retrofit lamp has an initial lumen output of 43,200 lumens and a mean lumen output of 35,200 lumens.

@worldwidehidcollectorusa3519 That’s interesting that the CMH lamp is slightly more efficient than the HPS lamp. The CMH lamp might also be move visible to the human eye at night than the HPS lamp due to scotopic vision.

I remember seeing a coated HPS in a nema head once, don’t remember when but I do remember. It started off as a whitish color, and I just assumed it was metal halide or mercury vapor, but then it started to gradually turn to orange and it was glowing orange like a high pressure sodium. Those coated HPS lights are rare, but I did see it once in a nema head. It was one of those ET shaped sylvania lumalux bulbs. It was definitely a high pressure sodium bulb. I also saw them a few times in like tall packs and wall packs, but I don’t usually see coated HPS lights. I probably never seen them in high wattages like yours. Usually when I see a coated HID lamp it’s either mercury vapor or metal halide. Not only is the coating rare on your HPS, but the wattage is too!

@@coolrobuxgaming I really want to get one of those ET23.5 lamps. A MV one especially (yes they made those).

[@coolrobuxgaming]

@@HIDLad001 It was weird seeing it coated tho, I see those mainly clear not coated. It was a coated high pressure sodium lamp, super rare.

[@coolrobuxgaming]

@@HIDLad001I looked at the street view and the 2024 street view, it looks like it has a clear lamp. So that coated one must’ve been relamped.

[@coolrobuxgaming]

@@HIDLad001I believe it was seen on my vacation many years ago, but I remember the street. The nema head still seems to be there, but the high pressure sodium bulb is a clear one now. But I do remember that exact fixture having coated HPS, so that bulb must’ve dyed or started cycling,

Cool lamp! And was that the cooldown at the end? Because WOW that was bright.

[@HIDLad001]

Yes it was, HPS lamps are very bright when switched off. But it is also the camera increasing the exposure.

[@rs12official]

@@HIDLad001 Interesting, didn’t know that. My mercury vapor doesn’t glow quite as much after being turned off.

[@johnrehwinkel7241]

It would be interesting to try adding a better IR filter to the camera too, to see how much of that was visible and how much near IR. Cool seeing the scope phosphor fade when you turned the light out. Also interesting watching the sodium glow become dominant during the low parts of the AC cycle.
