It produces parallel convergent rays across a plane horizontal surface and the rays are intense enough to be traced in natural light. Built in solid aluminum extrusion casing. Is supplied with a multi slit that produces either a single wide beam or choice of one , three or five pencil thin rays. It is supplies with a power adapter with all international safety certifications which can be plugged into the mains source 100-240V 50/60 Hz, or an external power supply may be used in the lab. It comes with a fixed lens, a slit with multiple sides and an adaptor.

The light is pretty strong. Simplicity is part of it's design. it's good enough to run many optics experiment, including lenses, mirrors and prisms. There is only one slot for a slide. You don't need an extra power supply, but there is place to plug one if you want to apply more or less voltage. Although, it gets hot inside, in the middle of the metallic case, the heat does not affect the slide in the front-end. It's a good buy, although it's a little expensive.
