This no-fuss meter stick optics bench light source will save valuable lab time. Clip the battery into its receptacle and the miniature lightbulb glows as bright as a candle. It’s that simple! The lightbulb is precisely aligned with the center of the lenses held by the meter stick lens holders so students won’t waste time cutting candle shafts to the appropriate height. And since there is no flame, it’s completely safe. Best of all, it won’t blow out in a drafty classroom. Pointed base provides an excellent position marker on the meter stick. Battery and miniature lightbulb are provided.
