Scored this less-than-a-year-old lamp today...was running cold cathode, hence the blackening.  Still works properly, though, for now anyway...

This is a design 50 lamp! I saw your design 50 too
streetlight98   [Apr 19, 2014 at 05:08 PM]
How come these aren't labeled as /DSGN50? My lamps in the case of 10 are all F40T12/DSGN50
A_lights   [Apr 19, 2014 at 07:41 PM]
These are the consumer/retail 2 packs instead of the case quanity
streetlight98   [Apr 19, 2014 at 07:45 PM]
Ahh I see. So the design 50 name still exists? I've never seen these sold in 2-packs. I've only seen the $40 10-packs at Lowe's. For 2-packs, my Lowe's sells GE lamps and for cases they sell Sylvania for T12 and GE for T8 (maybe Sylvania for T8 too).

I guess it's sorta like Philips T8s using the /741... codes on cases and the names like Natural Sunshine on the 2 and single packs.
streetlight98   [Apr 20, 2014 at 12:56 AM]
I don't see why we ned to use all these crazy names. Why not just /WW, /W, /CW, and /D (and maybe something like "/WD" for "white daylight" for 5000K?) instead of /CWP, /741, 841, and all these crazy terms. Just put all the extra "crap" on the package and save on ink with the etches lol.
A_lights   [Apr 20, 2014 at 01:04 AM]
I perfer /835 and names like that because they easilly tell what cri range is and kelvin, but I Don't like when they have Crazy names like closet and laundry! Whats color is that??!
joe_347V   [Apr 20, 2014 at 01:20 AM]
Yeah lol, the number codes and the names like /CW easily tell you what CRI and kelvin the lamps area. I've yet to figure out why GE thinks 3500K is called Office and Professional or something like that.
streetlight98   [Apr 20, 2014 at 02:20 AM]
eh if I wan to know CRI i'll look at the box. I don't know what those /741, etc codes mean so they're of no use to me. Laughing Yeah GE names their lamps based off the apllication, or what they think the application is. cool white is utility and basement or something like that. warm white is the famous Kitchen & Bath.
A_lights   [Apr 20, 2014 at 02:31 AM]
5= 50s CRI
6=60s CRI
7=70s CRI and so on.. 35 is the color
streetlight98   [Apr 20, 2014 at 02:50 AM]
ah so /735 is 70-79CRI 3500K? Is there a way to tell the exact CRI? So Design 50s are /950 then? that's actually not bad then. i like it now lol.
A_lights   [Apr 20, 2014 at 03:27 AM]
Something like that Razz
But for exact specs either on the box or spec PDF
GEsoftwhite100watts   [Apr 20, 2014 at 06:13 PM]
Yeah I see the naming thing all the time...I like seeing something like F40/950 as the ordering code...then maybe a "name" for the color.
Here's something I've been wondering about for some time now: could you use the older names and ordering codes (like "cool white" with a F40CW ordering code) on something like a /941 lamp as long as it meets the new efficiency and CRI rules?
streetlight98   [Apr 20, 2014 at 06:39 PM]
That's a good question. I was thinking to make etches simpler, have the manufacturer's name/logo and have like "F40CW Series 80" or something like that.
GEsoftwhite100watts   [Apr 20, 2014 at 06:47 PM]
I like that idea...or just something like
Sylvania
F40/950
40w USA
