Made the Right Way the Good Way

Bright Cool White Clarity

4100 Kelvin Cool White quad tube CFLs deliver balanced, neutral light that enhances focus and visibility. Ideal for offices, schools, retail, and task lighting, these bulbs provide true-to-life color rendering that supports productivity and comfort throughout the day. With 1200 lumens of output, your space shines bright without harsh glare.

Power and Efficiency

Each 18-watt Quad Tube CFL consumes a fraction of the energy of traditional incandescent bulbs, while producing the same brightness. With a 4-pin G24q-2 base and instant-on performance, these lamps deliver reliable lighting with up to 75% energy savings. Built for commercial and residential fixtures alike, they perform consistently across a wide range of applications.

Built to Perform

Designed for longevity, these compact fluorescent lamps are rated for 10,000 hours of life, reducing costly replacements and maintenance downtime. The quad tube design provides even, consistent light distribution, ensuring that every corner of your room is properly illuminated.

For the Love of Color

With a CRI of 82, these CFLs bring out natural tones in fabrics, finishes, and surroundings. The cool white spectrum adds clarity to workspaces, helping highlight detail in retail displays, classrooms, or office environments where accuracy matters.

Dependable Technology

Engineered with proven CFL technology, these lamps are free from the flickering common in older lighting. The 4-pin G24q-2 base locks in securely, ensuring steady performance in both open and enclosed fixtures. Mercury content is kept to a minimum, and the bulbs are designed for recycling at end of life.

Guardian of Prosperity

Running lighting day after day adds up — but these energy-efficient 18W CFLs make a measurable difference. A business replacing incandescent bulbs with these cool white CFLs can cut lighting expenses by over 70%, lowering not only energy bills but also AC and maintenance costs. When installed across dozens of fixtures, the long-term savings are substantial.

Built to Last

Each compact fluorescent lamp is manufactured with quality materials for consistent performance and longer service life. Unlike bargain alternatives, these lamps are designed to perform reliably in demanding environments, offering the confidence that your lighting investment will pay off.

Impactful Lighting

Choosing CFLs over incandescents reduces waste, conserves natural resources, and lowers greenhouse gas emissions. And when the time comes, upgrading to LED plug-in replacements for G24q-2 bases will extend savings even further — with up to 50,000 hours of life and maximum efficiency. As with every GoodBulb, your purchase supports a greater mission, providing clean solar light to families living without electricity.
