The Synergy 21 LED Retrofit lamp with manufacturer number S21-LED-001153 is a replacement lamp for conventional incandescent bulbs in the E14 socket format. The product is designed as a candle lamp (shape B35), clear-coated, and intended for use in indoor lighting fixtures. It is suitable for direct replacement installation in existing sockets supporting the E14 socket and provides a warm white light color of 2700 Kelvin. The lamp features a luminous flux of 470 lumens at a rated power of 4.5 watts, corresponding to energy efficiency class A+. Power supply is via the 230-volt mains, and the lamp is dimmable, with dimming functionality achievable using suitable Triac dimmers, such as the CBU-TED 61100.

Applications

The LED lamp is suitable for use in living and working spaces, as well as in facilities with decorative or functional lighting requirements. Due to its B35 shape and clear cover, it is frequently used in chandeliers, pendant lights, or wall-mounted fixtures where a classic candle shape provides an aesthetically pleasing appearance. The operating temperature ranges from -10 °C to +45 °C, allowing the lamp to be safely operated in typical indoor environments. Outside this temperature range, the lifespan of the LEDs cannot be guaranteed.

Functions and Equipment in Detail

The lamp produces warm white light (2700 K), creating a pleasant and inviting atmosphere. The CRI value of over 80 ensures good color rendering, making colors in the illuminated space appear realistic. With a beam angle of 360 degrees, light is evenly distributed in all directions, ensuring comprehensive illumination. The power consumption is 4.5 watts, with a luminous flux of 470 lumens. The energy efficiency class A+ indicates the high efficiency of the product, with energy consumption at 4.95 kWh per 1000 operating hours.

Technology Explained Simply

LED technology enables high luminous output with low energy consumption. The lamp uses LED chip technology housed in a clear-coated housing to evenly distribute light. The dimmable feature allows adjustment of brightness, with compatibility confirmed for Triac dimmers such as the CBU-TED 61100. Power supply is via the 230-volt mains, and the lamp requires no additional power supply or external control. The operating temperature range of -10 to +45 °C ensures stable operation under typical indoor conditions.

Compatibility and Accessories

The lamp is compatible with sockets of the E14 socket type and can be directly installed in existing fixtures supporting this socket. For dimming functionality, a Triac dimmer is required, with the CBU-TED 61100 model specified as suitable accessory. Compatibility with other dimmer models is not explicitly confirmed, so compatibility with other models cannot be guaranteed. The lamp is not intended for outdoor use, as no IP protection rating is specified.

Installation and Mounting

Installation is performed by simply screwing into an E14 socket. Before installation, ensure the power circuit is switched off to avoid electrical hazards. The lamp is designed for an operating temperature between -10 °C and +45 °C, so it should not be operated in enclosed, poorly ventilated, or excessively hot environments. Dimensions are a height of 100 mm and a diameter of 40 mm, ensuring a proper fit in standard fixtures.

Operational Advantages

The LED lamp offers high energy efficiency, leading to reduced electricity costs. The warm white light color provides pleasant illumination suitable for living and working spaces. The dimmable feature allows flexible adjustment of brightness for different usage scenarios. The long lifespan of the LEDs reduces replacement frequency, lowering maintenance effort and replacement costs. Compatibility with existing E14 sockets simplifies replacement without additional installations.
