LED, 5 mm, White
LED, 5 mm, White (Product Code: SLE/PHY/82) is a standard 5 mm white light-emitting diode used as a light source and indicator in school electronics circuits, science projects and physics practicals. It comes in a pack of 100, enough to equip a whole class, and the same 5 mm LED is available in a range of colours. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the 5 mm White LED Used For?
White LEDs give a clear, bright light, which makes them the natural choice when an experiment needs illumination rather than just an on/off signal. Students use them to light model houses and torches, to shine on a light dependent resistor in sensor experiments, and to compare the light and current of an LED with a filament bulb in LED characteristics experiment kit work.
A pack of 100 also covers science fair project kit needs in India's schools, where many pupils build lit displays at the same time. Always connect a suitable series resistor, observe polarity (the longer lead is usually the anode), and store the LEDs in their pack so the leads do not tangle or bend.
What to Specify When Ordering
- Number of packs of 100
- Any other colours from the 5 mm range, such as bright red or blue
- Whether you prefer board-mounted LED modules with a built-in resistor for younger classes

Frequently Asked Questions
How many LEDs are in a pack of LED, 5 mm, White?
Each pack of LED, 5 mm, White contains 100 standard 5 mm white LEDs. That is enough for a full class to build individual circuits, with spares left for replacements and project work.
Do the white LEDs need a resistor?
Yes, each LED, 5 mm, White needs a series resistor to limit the current, and resistors are not listed as part of the pack. Choose the value to suit your supply voltage, or ask us through the contact page for help.
How do I tell which way round to connect the LED?
An LED, 5 mm, White conducts in one direction only. The longer lead is normally the anode, which goes towards the positive side of the supply, and the flat edge on the rim usually marks the cathode. Reversed, the LED simply stays dark.
Are other colours available in the same 5 mm LED?
Yes, the standard 5 mm LED sold as LED, 5 mm, White is available in a range of colours, including bright red and blue listings. Mixed-colour orders can be quoted together, so state the number of packs of each colour in your enquiry.
Who supplies LED, 5 mm, White?
LED, 5 mm, White is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company provides these LEDs as components for school electronics and physics labs in India and international markets.
