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. Housing, sockets and ventilator are put together by Science Lab Supplies at its Plot 448, HSIIDC Industrial Area factory in Saha, Ambala, which manufactures the unit and quotes schools, colleges, tender contractors and distributors directly.
Specifications
Lamp, power and size figures for the 12 V parallel beam lamp are listed one per row. In short, it has a bayonet socket for clear 12 V/35 W incandescent lamps and a two-pole socket for 12 V/50 W halogen lamps, the rear handle sets focus and lamp position, and a built-in ventilator keeps the surface from getting too hot.

Applications and Experiments for the Parallel Beam Light Source
A straight, adjustable beam is the starting point for 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, as optics lab equipment for schools and colleges.
- NCERT Class 10 science, light: reflection by mirrors and refraction by lenses held in a Wooden Lens Holder.
- 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, powered from a regulated bench supply such as the AC/DC Laboratory Power Supply with its 1–15 V AC and DC steps.
Standard Scope of Supply
The light source is supplied with a 50 W halogen lamp and safety jack connectors for attaching the power supply. A 12 V AC/DC, 4.2 A supply to run it can be added as a separate line on the quotation, together with a bench or stand for mounting.
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 power supply can be included on the same quote.
Holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda.

Optics-bench requirements can be written up on the contact page or added item by item to the enquiry cart, with formal tender procedures set out on the lab tender page.
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. A suitable supply can be priced on the same quotation as the lamp.
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 with the unit.
Does the housing get hot?
A built-in ventilator cools the housing during operation so its surface does not get too hot. Switch off and let the lamp cool down before changing it or moving the unit.
Is Science Lab Supplies the manufacturer?
Yes. This light source is a product of the company’s own Saha, Ambala factory, where the housing is fitted with its sockets and ventilator, and quotations are sent by the manufacturer rather than a dealer.
