RS PRO BA9s Indicator Light, Clear, 24 V, 50 mA, 5000h

Tubular MCC lamps are suitable for applications in the automotive and gambling machine industries.

It is interesting how the bulb industry has changed during the last two centuries. Even though they are great light bulbs available on the market, there is still a requirement for Filament Bulbs lighting that brings reliability and a bit of history.

Today, we are proudly introducing our own branded RS PRO Filament Lamp acting as a functional light source for automotive or gambling machine industries where immediate light is required without any delays.

Their construction is quite simple as the lamps are encased in a glass bulb and consists of a thin coil of wire commonly known as filament. The high passage of current (50 mA - milliampere) increases filament temperature, allowing to provide superb efficiency. Our Filament Lamp provides clear light and delivers 2 lumens of bright output with an impressive lifetime of up to 5000 hours.

Depending on your needs in terms of voltage, current rating, diameter, lamp size or lens colour preferences, our wide range of Filament Lamps can fulfil all your lighting requirements.

Current, voltage and resistance combining create an ideal environment for Filament Lamps in:

• Automotive industry


• Gambling machine industry


• Car indicator


• Garden lights


• Paper lanterns

What is the temperature of the filament in the Light Bulb?

In a typical 120/130-volt bulb, the filament temperature oscillates around 2550 °C (roughly 4600 degrees Fahrenheit). So high temperature creates thermal radiation from the filament resulting in a significant amount of visible light.

RS PRO is our own-brand range of great-value products. Each part of every RS PRO product is stringently tested against demanding industry standards. We give it our seal of approval only when we're confident of exceptional quality. That's why RS PRO is trusted by engineers worldwide.

Operating costs, in the long run, are quite substantial, especially in comparison to other forms of lighting. On the other hand, filament bulbs provide less initial costs during the run, which is crucial for specific applications.
