Pifco Halogen Heater

pifco halogen heater
  • Any of the elements fluorine, chlorine, bromine, iodine, and astatine, occupying group VIIA (17) of the periodic table. They are reactive nonmetallic elements that form strongly acidic compounds with hydrogen, from which simple salts can be made
  • Denoting lamps and radiant heat sources using a filament surrounded by the vapor of iodine or another halogen
  • The halogens or halogen elements are a series of nonmetal elements from Group 17 IUPAC Style (formerly: VII, VIIA) of the periodic table, comprising fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
  • any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions
  • Halogen is a five-piece band from Perth, Western Australia. Formed in 1998 by two expatriate New Zealanders - Jasmine Yee and Frans Bisschops.
  • device that heats water or supplies warmth to a room
  • A person or thing that heats, in particular a device for warming the air or water
  • A conductor used for indirect heating of the cathode of a thermionic tube
  • A fastball
  • fastball: (baseball) a pitch thrown with maximum velocity; "he swung late on the fastball"; "he showed batters nothing but smoke"
  • A heater is object that emits heat or causes another body to achieve a higher temperature. In a household or domestic setting, heaters are usually appliances whose purpose is to generate heating (i.e. warmth). Heaters exists for all states of matter, including solids, liquids and gases.

Halogen spectrum -- whoops!
Halogen spectrum -- whoops!
This is the last spectrum picture for the moment... I broke my spectrometer. This is my 750 watt halogent light. As you can see, the spectrum is very smooth -- no spectral lines like the LCD or the CFL bulbs. That's because it emits light differently. Atoms and molecules have electrons in certain orbits -- when those electrons move from a higher energy state to a lower one, they emit a photon at a very specific wavelength. This causes spectral lines. That's how flourescent bulbs and LCDs work. There's another type of light emitted called black body radiation, and this light is caused by the heat of the object. Incandescent and halogen bulbs have a filament that gets extremely hot and gives off light in a smooth spectrum. So does the sun, and the heating elements in electric ranges and stoves. Our bodies give off black body radiation too, but the wavelength is too long for us to see. It's deep in the infrared. So a 750 watt halogen bulb gives off a LOT of heat. I had my spectrograph too close to it, and the razor blades I used to make a slit soaked up all that heat. I used hot glue to keep the razor blades in place. Hot glue melts at a fairly low temperature, so my razor blades fell off :-(
