Fluorescent lamp warning ?

[Puppin]

I bought some fluorescent lamps made by Philips in USA that present a
warning - Not for sale in USA.
Why this warning ?? Could this warning have any concern to the light
emitted spectrum ?
The lamps are 40W, cylindrical bulbs with 1.2m length, type F40D/XPT

Thank you.

If I had to guess, I would say it is becaues these lamps would not pass
the conditions of the Energy Policy ACT
(EPACT), a law in this country regulation both the efficacy and the CRI
of standard F40, U tube FB40, F96, and
F96HO lamps. Since the fine for failing to meet the provisions of the
law is $100 per lamp per day (If my memory
serves me) the manufacturer would definitely not want any issues. What
are the phosphor characterisitcs? I would
guess that the CRI of ht elamp is below 82 (a magical threshold beyond
which the lampis defined as a "special
purpose lamp" and exempted) and or has an LPW of less than 75 LPW.

That sounds correct, Jeff. The designation indicates that the lamp is an
F40/D (daylight color). That's an old halophosphor color with a CRI of75.
Philips (or any other lamp company) can make such lamps for export, but
cannot sell them in the U.S. because of ther low efficacy.

How could I know the type of phosphor the lamp uses and compare the
efficiency of different models and manufacturers.
Is there any site where I can find informations like these?

There is no hazard.

The warning applies to U.S. Federal energy conservation legislation
barring U.S. sales or importation of true 40 watt F40T12 general purpose
white fluorescent lamps with less than some certain color rendering index.
The energy legislation is known as EPACT. Its goal was to force people
to use 34 watt "energy saver" F40T12 or the newer F32T8 lamps.

Philips has an online lamp catalog in their web site. This mentions the
lumen output and the color rendering index of all of their white lamps.

As for phosphor type:

Old type cool white, white, warm white and daylight have halophosphate
phosphors. "Deluxe" types have a variation of halophosphates that peak
less in the yellow and have slightly more red and green than the standard
halophosphates. Colortone 50 is an improved form of this.

The TL8xx, TL7xx, "Ultralume" and "Advantage" lamps and any with their
"hi vision" phosphor have a triphosphor formula. All triphosphor lamps
have a strong narrow band in the orangish red around 611 nm and a strong
green band around 542 nm (except around 550 nm for the lower CRI "7" or GE
SP types). There is nowmally a weaker band in the blue-green and often a
broad band in the mid-blue. With the spectrum concentrated into the
primary colors, these lamps have the effect of making many colors look
brighter as opposed to the color-dulling distortions of the
halophosphates.

Thank you all for the help.

I wonder though. I see a lot of f40 systems lamped up with residential and
cool white deluxe type lamps. these are still 40 watts. I see not very much
use of the 34 watt lamps in my area. epact's intent to use 34 watt lamps
isn't working to well. I disagree with epact. the 34 watt lamps get too
dull after a while, 40 watt ones maintain much better. I do discourage the
use of cool white deluxe lamps because of their dullness, in favor of the f40
residential type lamps. The good side of all this, many new installations
are going with the 32 watt t8 systems. however many current small businesses
with older f40 systems are probably not going to switch to a t8 system,
because of costs, and the fact they don't care about saving energy. small
businesses usually just buy the cheapest thing: f40 residential or cool white
deluxe lamps.
