Conventional Fixtures - New Lamp: Ushio SPH575

[derekleffew]

More details at SPH 575 - Halogen - Entertainment - USHIO. C'mon, ship, give us all the dirt. Will this lamp make my thirty year-old Lekos out-shoot a SourceFour?


edit: I learned of this lamp from full-page ad on page 17 of the September 2008 issue of Stage Directions.

That just might put some of my older 5 & 10 degrees back into active service.

I don't think that this lamp is going to kill the source four...while it may help a lot of older fixture shoot further...there is no replacement for great optics. The S4 is ground to be much more optically precise then the older fixtures that it replaced. IMO that lamp will help people who have a large inventory of older fixtures, but it's not going to replace an S4.

You mean my 1KL's aren't going to be competitors of the S4?

No, your 1KL's aren't going to put the S-4 out of compitition unless you went Philips #6981P in them optically speaking.

Hmm, you know next time my Ushio rep calls me, gonna have to have a talk with her... Could sware I remember this lamp's coming to market but not sufficient to note it. On the other hand, the Osram HPR 575/115 lamp is the same output.


The HPR did best in testing the HPL lamp. Chief interests are filaments and reflectors here in that in the photo it kind of looks like this Ushio lamp also has an internal reflector but it's not mentioned in the specs. Filament wise, Osram made a mistake in doing a cc-8 FLK filament in its HPR lamp, the Ushio lamp did a GLC like cc-6 filament in it - though I would rather after that info if both companies would follow thru in size of filament as Philips has started to do as a norm. How close or better are either to a 9x8mm filament square area in size? (This of the Philips GLC Planar or Bi-Plane Compact Source Filament lamp.) Still cc-6 should be smaller in being a pin-point than that of a cc-8 in size. If it is a reflector I see in the lamp, that would be a better lamp.

If not an internal reflector there between base and filament glass hanger, that's up for grabs given the same output but better filament.

Hmm that spells play test for me and I'll do it ASAP.

Hmm, again... stumped on lamps, thanks - gonna have to speak to some sales people that call me monthly yet are not interested in other than presenting what sales I do per year as opposed to helping me buy more or keeping me informed in what's new or important to note....

Yep, that's business. Hopefully at some point I'll be able to constantly stay up on what's newest.

By the way on the BTH lamp.... anyone have problems in drop testing them? One of my two samples I dropped by accident and it went bye bye. Not as good of packaging on this lamp as a BTL of the same brand in my opinion and I did mention that to the rep., but as yet I'm probably the first to fumble finger the new lamp so it didn't go far beyond study into the problem.

Ship,
didn't I mention this lamp to you (the SPH) like 6 or 8 months ago?

Lightingguy32, indeed you did introduce us to this lamp in a post back on January 18, 2008, ([url="http://www.controlbooth.com/forums/lighting/6751-ushio-releases-sph-575watt-115volt-lamp.html"[/URL]). Ship went into detail about the construction of the lamp & comparisons to the GLC/GLA & HPL, and noted the transverse axial filament being better suited for PAR rather than ERS fixtures

I have been using these lamps as a GLC/GLA replacement in Wybron Nexeras. They are noticeably brighter than a GLC, although I don't have a light meter to document the difference. Although the Nexeras produce beautiful color, the optics are relatively poor compared to a Source Four, so it's difficult to offer a subjective evaluation on any difference in beam due to the SPH's transverse filament versus the GLC. Through my regular supplier, they are about $4 more per lamp than a GLC, but the slight difference in brightness is worth that additional cost, for me. The failure rate for these SPH lamps is approaching an unacceptable level, however. Typically, they will blow within 5 to 15 minutes of installation; if they make it past the first 15 minutes, they will go somewhere close to the rated life. I've lost close to 8 lamps, but my supplier has replaced most of them. After examining three of the failed lamps, Ushio claimed failure was not due to a lamp problem. While I have had some socket problems with the Nexeras, none of these lamps failed in fixtures with socket issues & the non-socket-issue failures had replacement SPH lamps which worked fine.

Maybe I'll wait another half year before buying SPHs. Sounds like a bad first run or something to me.

This lamp was invented and patented by Randy Wimberly, the inventor of the UniPar plastic PAR.

hmm, sorry, been a busy few months and I must have forgotton to look further into it though I know I had seen it before and it was in my lamp specs. chart. Interested now in looking into it soon.
