Spotlight Bulbs Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-5782
Jlab Export is a leading Spotlight Bulbs Manufacturer,and suppliers in India
Spotlight Bulbs (code EL-SLE-5782) are low-voltage bulbs for simple electric circuits in school science and physics practicals, listed in three ratings: 1.5 V at 0.2 A, 2.5 V at 0.2 A and 4.5 V at 0.3 A. Choosing the rating that matches the cells or supply on the bench keeps the bulb at its intended brightness. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Do They Compare with Other JLab Bulbs and Lamps?
| Item | Ratings listed | Other listed details |
|---|---|---|
| Spotlight Bulbs (EL-SLE-5782) | 1.5 V, 0.2 A; 2.5 V, 0.2 A; 4.5 V, 0.3 A | Three ratings under one listing |
| Lamp Bulb 2.5V 0.3A JLab | 2.5 V, 0.3 A | For miniature lamp holders |
| MES lamp Bulb | 1.5 V, 0.3 A | Miniature Edison screw (MES) lamp, supplied in singles |
| Lamps | 6 V, 5 W; 12 V, 5 W | Low-voltage lamps of higher power |
Choose the spotlight bulbs when your circuits run from one to three cells and draw a modest current; the MES and miniature-holder bulbs suit benches already fitted with those holders, and the 6 V and 12 V lamps suit low-voltage power supplies.
What Are Spotlight Bulbs Used For?
A small bulb is the simplest way to show that a circuit is complete. These bulbs are used in class 6 lessons on electricity and circuits, in tests that sort materials into conductors and insulators, in comparing brightness in series and parallel connections, and in class 10 electricity practicals. Match the rating to the source: the 1.5 V bulb suits a single dry cell and the 4.5 V bulb a battery of three 1.5 V cells in series. Running a filament bulb above its rated voltage makes it brighter but shortens its life, while a lower voltage leaves it dim. Let a bulb cool before removing it from its holder.
What to Specify When Ordering
- Rating and quantity of each — 1.5 V, 2.5 V or 4.5 V; the minimum order is 10 units.
- Holder fit — tell us the holders you use so the cap can be confirmed, or add bulb holders to the same enquiry.
- Circuit items — cell holders, connecting leads and switches are separate catalogue items.
Frequently Asked Questions
Which ratings are available?
Three: 1.5 V at 0.2 A, 2.5 V at 0.2 A and 4.5 V at 0.3 A. State the rating and quantity for each in your enquiry.
How much power does each bulb use?
Power is voltage multiplied by current, so at their ratings the bulbs take about 0.3 W, 0.5 W and 1.35 W respectively — far less than the 5 W low-voltage lamps.
Which holder do the bulbs fit?
The cap type is not stated in this listing. Tell JLab which holders you use, or order matching bulb holders with the bulbs, and the fit will be confirmed in the quotation.
Can I run a 2.5 V bulb on two cells?
Two fresh 1.5 V cells give a little more than its rating, so the bulb will be bright and its life shorter. For long classroom use, match the bulb rating as closely as you can to the cells or supply.
Who manufactures the spotlight bulbs?
JLab (Jain Laboratory Instruments Pvt Ltd) lists them as made at its Ambala works in Haryana, India, and quotes for them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a school science and laboratory equipment manufacturer in India, incorporated in 2017, with its works on Hargolal Road, Ambala, Haryana. Buying from JLab means dealing with the manufacturer rather than a trader: schools, colleges, dealers and importers order factory-direct, every bulb is visually inspected before dispatch, and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Lithuania in Northern Europe, Ivory Coast in West Africa, Austria in Western Europe, Poland in Eastern Europe and Argentina in South America.
Circuit Accessories
- Bulb Holder — a regular holder made to fit torch bulbs, also offered with a metal screw cup.
- Bulb Holders Regular — standard holders for wiring a bulb to a cell.
- Cell Holders Plastic — holders for one, two or four cells.
- Lamps — 6 V and 12 V low-voltage lamps.
