Restore your torch to working order with this replacement bulb from RS PRO. The krypton gas-filled bulb gives a pure white light that lets you see colours correctly. It offers a high level of brightness along with a long service life. The B3-type 11 mm bulb is olive-shaped, with a P13.5S prefocus lamp base. This designation tells you it's a single-contact miniature flange base, which is suitable for use in a wide range of portable lights including handheld torches, head torches and camping lanterns.
The bulb works at its best when powered at 5.4 V from a stabilised 50 Hz AC supply. For these optimal results, the bulb should be in the temperature range +20°C to +25°C and in an environment without the risk of mechanical vibration. You can use handheld torches in a wide range of settings, from camping to the medical and security sectors.
