Before anyone embraces the following suggestions per Mpotheau, please
consider a more intelligent approach.
The safest are fluorescent lamps, with a lens. Some facts.
1.) Fluorescent lamps are gas discharged. There's hardly any heat to speak of
that can ignite fumes or worse, your skin and eyes.
2.) A Lens of some type will capture any fragments of glass, if you ever drop
it hard enough to shatter.I seriously doubt that you will ever crack a
fluoresent lamp in your lifetime. Look at how the lamp locks onto the two
3.) More efficient use of electricity. one 26w = 100w incandscent. One
18w=one 100w incandescent w/ the coating.
4.) For example, there's portable task lights using one f40 biax lamp (a
common t5 size close u-bend lamp), Electronic ballast, Miro 4 aluminum
reflector, and DR acrylic prismatic lens that puts out 3600 lumens with a
task distribution of 0.5(!) SC, and 96% efficiency. THe whole system soaks up
just 42w. You would need a 250w incandescent to duplicate the lumen output,
and then the archaic bulb shape still could not be engineered well enough to
hit 0.5 SC, and 70% of that energy is nothing but heat.
5.) This is the 90's. Let's get with the green lights program and conserve

Subject: Drop Lights
Household bulbs should never ever be used in drop lights. The safest ones
are the rough service bulbs which are coated. These bulbs are nearly
shatterproof, a very important feature.
A Sunoco station around the corner from me was removing a gas tank. They had
the old low-tech drop light with a household bulb. As the tank was being
removed some spillage ocurred. One of the guys tripped on the wire for the
drop light sending it to the ground. The bulb shattered, making a spark and
setting the place on fire. Incredibly no one was hurt. Fortunately that
station is just around the corner from the fire department. And since there
was not a working fire extinguisher on the property the firemen had their
work cut out for them.
And, when you are working on your car it is not the worst idea to have a
functioning extinguisher handy.
