halogen-IR lamp source ?

[George Pontis]

I would like to get some of these halogen-IR lamps to try out. At least one in the
300W T3 linear style. I am not finding any on a quick search. Who makes them, and
where can a consumer buy them in small quantities ?

This is a 350-watt, not 300.

Thank you Victor.

"Q350T3/CL/HIR" was the full code and a search on it found many vendors.

Wattage of ones with IR reflection and designed to replace 300 watt
conventional ones is less than 300 watts.
I see these in some but not all hardware stores.

I am guessing that this one is intended to replace 500 watt conventional
ones.

Also: "discounted price" $25.55 each for at least 6. Life expectancy
is 1500 hours, as opposed to at least 2,000 for more conventional ones.
And I do not see any statement of actual light output, and I wonder if
this is a little short of that of 500 watt conventional ones.

It appears to me that at average USA residential electricity cost, these
lamops/"bulbs" pay for themselves if they meet life expectancy claims and
you otherwise use 500 watt ones and use them enough to have lamp/"bulb"
life no more than a few years. Otherwise use the money to invest that
much more into any mutual funds you invest in.

That is right.

I don't know which brand BulbMan is selling, but the GE 500-watt
linear halogen incandescent, Q500T3/CL, is rated for 10550 lumens and
2000 hours while the GE 350-watt HIR version, Q350T3/CL/HIR, is rated
for 10,000 lumens and also 2000 hours.

Also: "discounted price" $25.55 each for at least 6. Life expectancy
is 1500 hours, as opposed to at least 2,000 for more conventional ones.
And I do not see any statement of actual light output, and I wonder if
this is a little short of that of 500 watt conventional ones.

See above. The GE HIR lamp is rated for 5% less light.

The 150 watt savings times 2000 hours is 300 kWh saved. At $0.08 per
kWh the lamp saves $24 over its life. I know we pay far more than
$0.08 per kWh.

conventional ones is less than 300 watts.

To replace a linear 300-watt halogen lamp GE makes a 225-watt linear
HIR, their, Q225T2CL/ULTRACD, which has the same output but longer
life than their 300-watt linear halogen, Q300T3/CL/CD, so the output
of the 225-watt HIR would be higher than the non-IR lamp if the HIR
lamp was designed for the same 2000-hour life.

Q225T2CL/ULTRACD 5950 lumens and 3000 hours
Q300T3/CL/CD 5950 lumens and 2000 hours

The 150 watt savings times 2000 hours is 300 kWh saved. At $0.08 per

$0.08 per kWh.

It was a struggle for GE to meet the rated lumens of their own 500 watt
linear halogen with the 350 watt IR version, so in the advertising they
talked about light output from the 350 watt lamp matching the output of
competitive lamps knowing that their competition was the poorly-performing
500 watt lamps showing up in torchiers.

Thanks Terry. I noticed that my Philips 2001/2002 print catalog gives
the output of their 500-watt linear T3 halogen lamp, 500T3Q/P/CL as
9500 lumens, vs. 10550 for the GE, so the GE 350-watt HIR T3 beats the
Philips 500-watt non-IR halogen. (However, I did not check the Philips
Web site to see of they currently claim higher output.)

In our case (N. California), the electricity rate is tiered starting at $0.114 per
KWH, but half our usage is at $0.22 per KWH. Thus the savings increase to $66 over
the lifetime. Specialty Optical Supply sells the GE version of Q350T3/CL/HIR for
$18.75.

Q225T2CL/ULTRACD 5950 lumens and 3000 hours
Q300T3/CL/CD 5950 lumens and 2000 hours

Thanks!!!

So this means 26.44 lumens/watt with prospect for slightly more as an
improvement over 17.63 lumens/watt.

Touche...

I pay almost $.14 per KWH, but my rate is worse than average. I am
under the impression that the USA average is about $.10.

As for me, if investing into an interesting lamp is borderline in
projected return in comparison to adding that money to my next purchase of
shares of a mutual fund, I would buy the interesting lamp.

But somehow, for investing into alternatives to conventional halogen for
torchiere lamps (which conventionally consume 300 watts of electricity, as
in I consider them minor room/ceiling heaters) I think I would do better
with fluorescent versions that achieve something more like 60 lumens per
watt as opposed to improved halogen ones that achieve upper 20's as in
improvement over 20.

I meant 26.44 improving upon 19.8 rather than upon 17.63 (It's late!)

In the UK, they are available from the larger B&Q stores (looks exactly
like Home Depot for US readers, but the two have never been anything to
do with each other). Likewise the 500W equivalent (375W IIRC). They only
seem to be in stock perhaps half the time though.
