About this product
A small incandescent bulb rated at 3.8 V and 0.3 A, designed for classroom physics experiments and circuit demonstrations. Its small base is typically E10 or similar. Because it draws more current than an LED, it must be driven through a suitable supply, resistor or transistor when used with microcontrollers.

Frequently asked questions
What is the price of Mini Incandescent Bulb 3.8V 0.3A for Physics Experiments in Egypt?
Mini Incandescent Bulb 3.8V 0.3A for Physics Experiments currently costs 15 EGP in Egypt.
Where can I buy Mini Incandescent Bulb 3.8V 0.3A for Physics Experiments in Egypt?
Mini Incandescent Bulb 3.8V 0.3A for Physics Experiments is available from Ekostra. Compare the offers above to find the best price.
Can I connect it directly to a 5 V supply?
Not directly. To run it at 3.8 V and 0.3 A from a 5 V supply, add a series resistor of about 4 ohms rated at least 0.5 W to limit the current to roughly 0.3 A.
Can I drive it directly from an Arduino pin?
No. A 0.3 A load is far above the roughly 40 mA absolute maximum per I/O pin on most Arduino boards. Switch it with a transistor or MOSFET rated for the current, powered from a separate supply, and drive the transistor's base or gate from the pin.
