RS PRO Yellow Indicator Lamp Multichip, 28 V AC/DC, BA9 Base, 10 mm Diameter 204-451

RS PRO 204-451 Yellow Indicator Lamp Multichip is a high-performance LED indicator lamp designed for industrial and electrical applications requiring reliable and visible signal indication. Its BA9 base enables simple replacing of incandescent filament lamps with a low power multi-chip LED alternative delivering superior brightness and energy efficiency.

The lamp contains 8 multi-chip LED elements combined with a bridge and current limiting resistor, allowing it to be powered by either 28 V AC or DC. When connected to a DC supply, the positive connection must be made to the base contact. Its satin chrome reflector enhances the light output, while a 180° viewing angle ensures the indication is clear from wide perspectives.

With a peak wavelength of 585 nm, this indicator lamp produces a vivid yellow light suitable for control panel indications, signaling devices, or status indicators in industrial machinery, laboratory equipment, and automation systems.

Multi-chip LEDs provide several advantages over traditional filament lamps, including significantly lower current consumption (between 50% and 65% less), lower heat dissipation, and a high degree of immunity to mechanical shock and vibration. The rated life extends up to 100,000 hours, ensuring minimal maintenance and replacement costs.

Care should be taken that the operating voltage does not exceed the rated voltage by more than 10%, as higher voltages may shorten the life expectancy of the lamp. Its compact dimensions of 10 mm diameter and 28 mm length allow easy integration into existing indicator lamp holders and panels.

Equipped with 8 LED chips for enhanced brightness and reliability. Designed with a satin chrome reflector to improve light output efficiency. Compatible with both AC and DC power supplies, providing versatile installation options.

Features a viewing angle of 180° for wide visibility in instrumentation panels. Peak wavelength at 585 nm ensures a distinct yellow light output. Durable multi-chip LED construction offers longer life hours of up to 100,000 hours.

Low current consumption between 50% and 65% reduced compared to incandescent lamps. Operating voltage must not exceed 10% above rated 28 V to maintain lamp longevity. Highly resistant to shock and vibration, suitable for industrial environments.

Compact design with 10 mm diameter and 28 mm length for easy panel integration.

This indicator lamp is ideal for various industrial, laboratory, manufacturing, HVAC, and electrical control applications where bright and reliable status indication is required. RS PRO products offer trusted performance and quality in electronic components.
