chamber lamp

Definitions

1. 1

   An oil lamp designed for indoor use.

   • A chamber lamp burned in the fire place: by this light, as he leaned against the feet of the bed, he perceived his uncle slept.
   • The waiter had also left upon the hearth a porcelain tower-shaped construction, through the loopholes of which struggled a feeble light — in other words a French chamber lamp.
   • Olive oil lamps are commercially available today. I have two. One is called an olive oil chamber lamp and is from Lehman's in Ohio. It is a very practical jarlike lamp with a handle, which makes it easy to move from room to room.
2. 2

   An indicator light associated with a chamber.

   • Position the battery toggle switch (10) figure 4-5 to BATTERY. If the fog chamber lamp illuminates, the indicator is operational.
   • When the battery is inserted into the MH26/26a charger properly (it's impossible to insert it incorrectly), the battery chamber lamp (labeled L and R) above each chamber will flash slowly while the battery is being replenished.
   • In a classic example (e.g., Skinner 1938; Herrick et al. 1959), a rat's lever presses produce food when a chamber lamp is turned on, while presses in the absence of the light produce nothing.
