We use the 60s for our work lights in the auditorium. 8 of them do the work of the 12 500W incandescents. They've been in operation for about a year now with no issues.
Hi Dad; May I ask where you purchased yours? Home Depot, Lowes, a wholesaler, a stage lighting supplier, or ? ? ?
Thank you very much for your post.
Toodleoo!

The 60W ones are not dimmable. And by that I mean they DO dim (albeit poorly), but they aren't designed to, and they will fail early as a result as the driver wasn't designed for it an cannot handle the heat.
The 90W FLx on the other hand IS designed to dim, and has a Dimmable Driver. ETC tested them for us on their various solutions and we have that document available for download/viewing on our website. So- if you are just putting them on an on/off switch-- FL 60W unit is fine. If you want to dim them, go with the FLx 90W unit.
It dims via mains voltage (no DMX) only. You can use up to 4 on a dimmer (2.4K) without issue. They won't dim ALL the way out like DMX fixtures can do. They cut out in the 10%-15% range (1% reading on the board, but roughly ~10-15% lumen output).

4 fixtures at 90 watts max? I usually assume about 50% load for LED but that would be 13 or so.

Apologies for multiple posts - another question now that I found the ETC document. Any suggestions for a wall box dimer retrofit - 6 of the FLx 90 - currently a 1500 Lutron incandescent only.
A quick google of Kreios ETC Dimming hits this document as the first entry.

Great - I found what I wasn't looking for and you want it. Try: http://kreios.osram.com/kreios/en/ for the group and heres the profile with links to data: http://kreios.osram.com/kreios/en/kreios-profile/index.jsp
Not sure these are available in US or CA. All new to me. At a quick glance, they look a little less powerful than the S4 575 and no idea on optics. Interesting though. Look pretty new.
Mark - will we see these at USITT? Sneak one in at least?

Yes - silly me - I looked for Osram Kreios FLx and got buptkus.
The internet, and any technical documents for that matter, are lot like Jeopardy!. The answer is staring you in the face if only you know the right question to ask.

I stand corrected. I had misremembered the email from my engineer. Here is his quote: "FLx absorbs ~2.5A with leading-edge dimmers and ~1.2A with trailing-edge dimmers. So depending on the dimmer type, on a 10A channel I would connect a maximum of 3 fixtures (LE) or 5 fixtures (TE)".
So scaling it up for 20A dimmers: ~6 fixtures max on 20A (LE) dimmers, and ~10 fixtures max on 20A (TE) dimmers. Boy life was simpler back in the Halogen days....

We showed these three new fixtures in our booth at LDI this October, and will be showing them again at USITT. Please stop by the booth and we'd be happy to demonstrate them. They've been available for the past few weeks. Very bright for only 80W.
The web address for information on these in the USA is here at the Sylvania.com website below:

As far as online retailers, the best price I've seen is at BMI:

I'm currently using 4 of the 90W units on a Leprecon ULD-360 for a blinder effect (25% was deemed sufficiently blinding). On was at 13% on an Express, off was a 7% on an Express, running faders up/down by hand for that test. After this production closes and the electrician and dimmer unit shows up, they're going to be installed as house lights running on a 12 channel/10 amp ETC Smartpack.
