The UniBulb Halogen 78mm R7S Linear 2250lm 120W 2900K (Warm White) Dimmable – Pack of 4 is a high-performance lighting solution designed for applications that require strong illumination, elegant colour rendering, and dimming flexibility. With a sleek tubular shape and double-ended R7S base, these halogen bulbs are widely used in floodlights, security lights, floor lamps, uplighters, and other linear lighting fixtures. This pack of four ensures you have the replacements or spares you need for multiple fittings or frequent usage.
Each bulb delivers a powerful 2250 lumens of light output, providing clear, bright illumination that is ideal for both domestic and commercial use. Whether you are lighting up a spacious living room, garden area, display feature, or workplace, this level of brightness ensures visibility and comfort. The 2900K warm white colour temperature offers a welcoming and familiar light, similar to traditional incandescent tones, but with the enhanced clarity that halogen technology provides.
The 120-watt power rating ensures instant, full brightness without any delay. This makes these bulbs particularly suitable for outdoor security lights or workspaces where consistent, strong lighting is essential the moment the switch is turned on. They are also widely used in architectural or accent lighting, thanks to their ability to highlight features or deliver focused beams of light across a wide area.
One of the standout features of the UniBulb R7S linear halogen bulbs is their dimmable capability. Compatible with standard halogen dimmer switches, these bulbs allow you to adjust the brightness according to your needs and preferences. Whether you're aiming for a softly lit ambience or maximum brightness, dimming provides greater control and versatility, making these bulbs ideal for multifunctional spaces such as living rooms, event venues, or hospitality environments.
Each bulb is crafted with a clear quartz glass casing, which enhances heat resistance and ensures safe operation during extended use. The slim linear design allows them to fit easily into fixtures with narrow or recessed housings. The R7S double-ended cap ensures a secure and stable connection, reducing the risk of flickering or loose fitting, which can occur in lower-quality alternatives.
This Pack of 4 offers both convenience and value. Whether you are stocking up for future replacements or outfitting multiple fittings at once, this multi-pack reduces the need for frequent shopping and ensures uniformity across your lighting scheme. It is especially useful for maintaining consistent light output in rooms or areas where multiple bulbs are used in a single fixture or arrangement.
Halogen lighting is known for its accurate colour rendering, which means objects appear true to their natural colours under this type of illumination. This makes the UniBulb R7S ideal for spaces where visual clarity and aesthetics matter, such as retail displays, galleries, or detailed task areas.
The bulbs are built to high manufacturing standards, delivering consistent performance with reliable ignition, minimal maintenance, and an extended operational life — up to 25 years depending on usage. This durability makes them a dependable choice for users who require powerful lighting with minimal interruptions.
In summary, the UniBulb Halogen 78mm R7S Linear 2250lm 120W 2900K Dimmable – Pack of 4 offers dependable brightness, warm and natural light quality, dimming flexibility, and a secure fit, all in a format that suits a wide range of applications.
