Lamp Black Light
What kind of light or lamp should I use for a science fair experiment on heat absorption?
The experiment uses jars filled with water and each containing a thermometer. The jars are wrapped in paper...white, shades of grey, and black. Temperature is measured over time. I originally listed "a sun lamp" in my materials list, but now I'm not sure if that's best for angle variations (keeping this constant) and where to get one.
Any thoughts or ideas regarding things I should consider?
I think the halogen light might be good idea. Heat lamps are designed to but out a lot of infrared, and some (not all) coloring materials have quite different absorption in infrared. I have used infrared viewers in photographic darkrooms and a few things that are black in visible light are very bright in infrared. If you were unlucky enough that your black paper was colored with one of those dyes, it could really mess up your results. While halogens also emit considerable infrared, the do have a higher proportion of visible light than a heat lamp.

Installation and use of black light
In recent years, the use of black light on the increasing number of fisheries, not only can play for the fish to provide animal feed, feed commodity economy, reduce fish costs, increase efficiency for the role of farmers; but also prevent pest damage on crops, fish ponds and install the black light so that can play a "double benefit" effect. Here's what the installation and use of black light:
Is a special black light lamp, the lamp emitted UV light harmful to people and fish, but brightness is small, low illumination, so the light of this light is called "black light." Tests show that many insects (large some agricultural pests) on the 3000 ~ 4000 Epaud long the most sensitive ultraviolet, has the largest phototaxis, while the emission wavelength black light around Egypt in 3600, which is a lure insects ideal light sources.
Black light trap to many insect species, including grain, cotton, oil, fruit and other major pests, such as the corn borer, Helicoverpa armigera, mole crickets, armyworm, beetle, red aphids, cutworms, Taiwan, heart worms, etc..
If you install the black light in the aquarium, and set the collision facilities in the light, you can touch falls fishpond in insects. This will provide fodder for the pool of fish, but also to kill agricultural pests, receive fish, destroy the dual effect of insects.
First, equipment: ultraviolet light from the AC power, black light tubes and accessories, rain cover, block worm plate, truss and other several parts. Black light tube shape and the same structure and general fluorescent tube, but the phosphor coating the inner wall lamp different. Currently used black light tubes provide 20 watts and 40 watts of two. Black light accessories, including rectifiers, relays and switches. Accessories specifications should be the same with the black light tube specifications. Covers is to prevent the black light equipment for water pipes and fittings should be located at the top of the lamp and its accessories. Glass plate can block worms and other things made of hard transparent, tube length and the same length, each tube plate 3 can block worms? 4. Stands can be wood, bamboo, iron tripod production.
Second, the principle of black light installation installation is safe, economical, simple and effective. Black light can be placed in the central pool, if the surface larger in (turtle class), fish or regular activities focus on areas where a few were set in order to facilitate fish eat insects. Black light height to fit, not too high from the surface of the water, so as not to affect the trapping effect; too low, so as not to break something when prey fish lamp. Can take the black light lamp adding a common method to improve the efficiency of trapping. The experiment, in a black light adding an ordinary 60-watt light bulb. Trapping efficiency can be increased from 0.7 to 3.2 times.
Third, using the black light of the considerations. Black light trapping effect of climate conditions, in the absence of rain, no wind [or a light breeze) in the case, the trap catches more; induced in heavy rain or strong winds were minimal. So. Should decide whether to turn on the lights as the weather conditions. Under normal circumstances. The activities of various insects at night, the law is different. Therefore, the conditional areas should turn on the lights all night.
