Their Micro-Lume fluorescent lamps range in length from 50mm to 300mm and in diameter from 5.6mm to 8.0mm. They have the following colors:
They also have a line of UV lamps ranging in length from 25mm to 240mm and in diameter from 3mm to 9 mm. These are described as "narrow-band", and are available in several different wavelengths. Go for something 345 to 400 nM.
Straight from JKL, the visible lamps cost about $10 apiece. Power inverters go for $15. I have also seen JKL fluorescent lamps and inverters at Fry's Electronics and All Electronics.
As of 5/2000, All Electronics offers the following lamps:

Tiny, inexpensive, long life, cool-running, easy to use. Could you ask for more? It's scary! I'll bet that there are hundreds of haunt applications for colored fluorescent lamps the size of a pencil.
All of these lamps require special power supplies. JKL carries inverters that run on 5V, 14V, and 24V.
This page from the
catalog (#203, Spring 2003) shows various inverters for cold-cathode fluorescent lamps.
The stick is activated by bending. This breaks a small glass vial inside the plastic tube, allowing two chemicals to mix, producing light. The light is produced without heat or flame, giving it the nickname "cold light". It works rather like the chemical light emitted by a "fire fly" or "lightning bug".
Glow sticks are available in various colors. Some are very bright and last for half an hour. Others are not so bright and last for hours.
Glow sticks are handy anywhere you need a small, disposable, self-contained light source. They are especially nice because they do not produce fire, sparks, heat, or smoke. You should have some in your earthquake kit. They have many haunt uses.
You can also get novelty light sticks, in the form of rings, necklaces, and buttons.
If you put a light stick in bowl of dry ice and water to color the fog, the light will soon fade away as the light stick gets cold.
If you have light sticks in your emergency supplies, you should pay attention to the expiration date stamped on the pouch. Use the expired sticks in your haunt and buy new light sticks for your emergency kit.

We have a whole page devoted to light emitting diodes.
When all the photons in a monochromatic light beam are synchronized, the beam is said to be
This is what makes LASER light unique.
This is a small Helium-Neon gas laser given to me by a friend. Thanks, Jeff!
The high-voltage power supply is built into the black plastic base and sealed with epoxy. All it needs to run is 12VDC.
Traditionally, LASER light has been costly and/or difficult to produce, requiring flash lamps, high voltage discharge, or other other fussy machinery. All of that changed with the invention of the LASER light emitting diode.
CAUTION: Because LASER light is coherent, it packs a punch far greater than its brightness might suggest. LASER light can be dangerous. Keep it away from eyes.
