on ecolux bipin fluorescents, you can check the inkjet printing on the tube, there is a date code there. it should say 04, 05, 06, 07, etc which correspond to the last 2 digits of the year.

May all the great lighting technologies have their place in history.

That 09 may mean that it was made in 2009, I'm pretty sure that's what Dave meant! but I could be wrong! Would be nice if we could figure out the month!

I might have been a little off in the description, the "8" is the year. This lamp was manufactured on the 94th day of '08. Some of GE's lamps do have the 07, 08, 09, etc as the year.

Thanks for the help I might have just the place for this lamp. It appears to have low hours. It's twin already has some blackening on it. Guess it got used a lot more.

What's interesting is that at Ace, these lamps retail individually for $3.99. THE SAME EXACT LAMP, manufactured by G.E., branded with the Ace logo, with the same color temp., can be purchased in a 2-pack for $3.00 even. And yet, people still buy the G.E.s because of the brand association! In my personal opinion, out of all the "eco-friendly" low-mercury assortments of lamps by different manufacturers, G.E. Ecolux tubes are by far my favorite.

I don't have a favorite linear fluorescent lamp's brand as I don't use them often. The only place that has the 4's in my house is in the kitchen. Those have been in there a long time, I actually forgot what brand are they including whether they're ecos or not! Need to check them out. That's a long time for modern lamps (since around 2005 or earlier) especially the fact they're being used constantly.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

What is the LL (Long Life) designation for? Is it that GE started making Residential lamps 20k hours? Early ones were 15k hours.
