Light Bulb
Product Code : SCL-CL-11868
Light Bulb (SKU SCL-CL-11868) is a 9 V, 0.2 A bulb mounted on its own stand, serving as the load and visual indicator in school electricity circuits. It comes plug-and-play with two spare bulbs and suits Class 6–12 science and physics practicals as well as basic ITI electrical exercises. Orders from schools, colleges, training institutes, distributors and tender contractors are handled by Science Lab Supplies at Ambala, India.
Specifications
The rating, mounting and spares of this stand-mounted 9 V bulb are listed row by row below. In short, the bulb is rated 9 V and 0.2 A, which works out to about 1.8 W, and sits upright on a stand so it can be wired into a bench circuit; two spare bulbs come with it.

Applications and Experiments for the Light Bulb
A stand-mounted bulb lets students see whether current is flowing and roughly how much. It fits the electricity chapters of NCERT Class 6–10 science, Class 12 physics circuit work and introductory ITI electrician practicals on loads and connections, and it can be swapped between circuits during a single lesson.
- Class 6: showing the difference between an open and a closed circuit, alongside the bulb holder on a Junior Circuit Board.
- Class 7–8: testing conductors and insulators placed in the circuit.
- Class 10: comparing brightness of bulbs in series and in parallel, as with the three bulbs of the Apparatus for Studying Circuits for Series and Parallel Connections.
- ITI electrician trade: wiring a lamp load with a switch and measuring its current with the digital Tester Input Plugs.
Keep the supply at or below the 9 V rating; a higher voltage can burn out the bulb.
Standard Scope of Supply
Each unit is supplied as the light bulb fitted on its stand, together with two spare light bulbs. The power supply or cells, the switch and the connecting leads are separate items, and any of them can be listed line by line on the same quotation as the bulb.
Packing, MOQ and Lead Time
You may ask for one bulb unit or a set for every bench. The quotation lists packing, delivery time and price for exactly that number, and further school chemistry lab equipment in India or physics items can be priced alongside it in the same document.
With an Importer-Exporter Code in place, Science Lab Supplies can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). For a price on bulb units, message the team from the contact page or save them to the enquiry cart; schools issuing a tender can begin at the lab tender page.
Frequently Asked Questions
What is the rating of this light bulb?
It is rated 9 V and 0.2 A, about 1.8 W. Run it from a source such as cells or a DC bench supply set no higher than 9 V, so the filament is not overloaded.
Are spare bulbs included?
Yes. Two spare light bulbs come with the stand-mounted bulb, so a class can carry on with the practical when a filament fails part-way through the lesson.
Who supplies the Light Bulb?
Science Lab Supplies prepares the quotation and dispatches the bulb from Ambala, India. Schools, colleges, training institutes, distributors and tender contractors can ask for single units or a set for every bench.
What else do I need to light the bulb?
A voltage source of up to 9 V, connecting leads and, if wanted, a switch. These are separate items that can be added to the same quotation as the bulb and its spares.
Related Lamps, Holders and Circuit Items
The bulb needs a source, a switch and leads before it will light, and resistors let students see how brightness changes with current. These items from the Chemistry Lab and Physics Lab ranges complete a basic circuit bench and can be quoted with the bulb on one enquiry.
