Sleazy Marketing on GE Fluorescent Packages

Sleazy Marketing on GE Fluorescent Packages

Click to view full size image

First of all, I’ve never seen a daylight lamp that was 6250k. Most all standard daylight lamps are 6500k. Second, why would they even bother with this? I’ve never seen anyone actually pick up a package of fluorescent lamps and read the specifications. Most people, especially the average consumer, have no idea about the differences or subtitles of fluorescent lamps.

There must be a difference between Daylight 6250K and GE Daylight 6500K.

I have no doubt one existed at one time, but the problem is that 6500k is standard daylight, and the marketers deliberately compared the GE daylight to an unusual lamp in order to make their’s look better than the competitors.

There is quite big visible spread between same rated lamps from different manufacturers, shifts as the lamps age etc. I'd say more than 250K difference. Though all the lamps are rated the same 6500K

The average user does not know anything at all and can at most match Watts or ask to give him "Yellow" or "White" lamp (most of them dont even know that an "inbetween" color like 4000K exists). GE here tries to put the data straight, its the users that dont do anything with it..



I wonder what's the phosphor of that "GE Daylight" ?

The light output of most 36W/765's i seen is 2500Lm (the highest i seen is 2700lm from a Chinese manufacturer)

40W/765's are between 2300..2500 Lm

And GE (Tungsram) both 36W/ and 40W/765 are 2350 Lm

Yet it still have 75 CRI same as all ordinary 765's ?

Here in the US, lamps are usually rated on initial lumens, not average lumens. The mean lumen output of this lamp is 2775lm, which matches more closely with the 765 lamps.
