Parallel Beam Light Source
Product Code : LSK-PL-10348
Parallel Beam Light Source (SKU LSK-PL-10348) is a lamp housing that emits a bright, straight beam for optics experiments and demonstrations. It is supplied with a 50 W halogen lamp, takes 12 V lamps in two socket types, and mounts on an optical bench or laboratory stand by a 10 mm mounting tap. Science Lab Supplies manufactures the light source at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area) and delivers direct to schools, colleges, tender contractors and distributors.
Specifications
The housing has a bayonet socket for clear 12 V/35 W incandescent lamps and a two-pole socket for 12 V/50 W halogen lamps. Turning or sliding the rear handle adjusts focus and the lamp’s horizontal position, and a built-in ventilator keeps the housing surface from getting too hot.

Applications and Experiments for the Parallel Beam Light Source
A straight, adjustable beam is the starting point for most ray-optics work on a bench: finding focal lengths, tracing refraction and producing images through lenses and mirrors. Mounted on a rail, this lamp becomes the light end of an optical bench setup, a staple of optics lab equipment for schools and colleges.
- NCERT Class 10 science, light: reflection by mirrors and refraction by lenses.
- Class 12 physics, ray optics: focal length of lenses and mirrors on an optical bench.
- B.Sc. optics practicals needing a parallel or focused beam.
Standard Scope of Supply
The light source is supplied with a 50 W halogen lamp and safety jack connectors for attaching the power supply. The 12 V AC/DC, 4.2 A supply it needs is a separate item, and it can be added to the quotation together with a bench or stand.
Packing, MOQ and Lead Time
Request a quote for one lamp or for a full optics lab, and the quotation will list packing, delivery time and price for that exact quantity. Benches, mirrors, gratings and a matching power supply can be included on the same quote.

Frequently Asked Questions
What power supply does the Parallel Beam Light Source need?
A 12 V AC or DC supply capable of 4.2 A, connected through the safety jack connectors on the unit. The supply is not part of the listed item.
Which lamps can it take?
Clear 12 V/35 W incandescent lamps in the bayonet socket, or 12 V/50 W halogen lamps in the two-pole socket. A 50 W halogen lamp is supplied.
Does the housing get hot?
A built-in ventilator cools the housing during operation so its surface does not get too hot. Let the lamp cool down before changing it.
Is Science Lab Supplies the manufacturer?
Yes. The unit is built in the company’s own factory at Saha, Ambala, and quotations are sent by the manufacturer rather than a dealer.
