How to select the Krypton bulb flashlight?
Does anyone know how the ratings of tension for a flashlight Krypton work bulbs? Seem to suggest that a flashlight 2 batteries (two AA batteries 1.5 V) should use a bulb 2.2V Krypton. Is this true? If yes, why — this correct? The nominal voltage of a light bulb is often less than the battery voltage. The reason is that during the preparation for most types of batteries, as Alkain and carbon-zinc battery internal resistance causes the voltage drop of output. If you used a 3-volt bulb with Cell 2 AA is very low flash point higher (for the same nominal power) have greater strength and power to reduce battery voltage weak. The best way to buy a light bulb is based on the number of cells (2-AA 3-C Cell, etc.) be warned that some battery chemistries, including rechargeable types NiCd, NiMH and lead-acid does not have much of a voltage drop. I learned all this because I built a lighthouse for my bike with a lead-acid battery 6 volt Krypton bulb purchase and designed for a lantern battery 6 v
