; | ;bin: an LED classification that describes the performance of a particular [[LED]] model - Flux, tint, and Vf. Example: UV1J. [[Cree]] uses bin numbers P4, Q2, Q3, Q4, Q5, R2, R3, R4, R5, S2 each denoting a roughly 5% increase in output. As LED's come out of the factory, they are tested and put in actual bins based on their performance. | ||

;C: capacity - the charge/discharge rate in an hour. For instance discharging a cell rated 1000mAh at 1C means drawing 1000mA and it should last 1 hour; at 0.1C it would draw 100mA and last 10 hours. | ;C: capacity - the charge/discharge rate in an hour.

;corona: - the area of transition between a beam's central hotspot and the area of spill. The corona becomes more prominent as the reflector surface is made rougher or more heavily textured, and also as the distance of the light emitting surface from the reflector focal point increases. | ;corona: - the area of transition between a beam's central hotspot and the area of spill.
