Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Feit’s 42 W PL CFL bulb is engineered for reliable, high-output illumination in fixtures that use the GX24q-4 base. With a frosted finish and a crisp 4100 K cool white color, it delivers a task-focused glow that keeps workspaces, retail surfaces, and public areas looking bright and inviting.

Key benefits that matter in real spaces

  • Bright, steady light: approximately 3000 lumens for strong, even coverage across work surfaces and display areas.
  • Long service life: rated to about 10,000 hours, meaning fewer replacements and lower maintenance in busy environments.
  • Compact PL form: 1.8 in. diameter and 6.59 in. length, designed to fit a wide range of PL fixtures with GX24q-4 bases.
  • Glare-reducing finish: frosted coating minimizes harsh reflections for comfortable, all-day viewing.
  • Neutral, daylight-like color: 4100 K cool white delivers a clear, professional look ideal for offices, workshops, and retail spaces.
  • Versatile placement: suitable for indoor and outdoor applications in both commercial and residential settings.
  • Simple operation: non-dimmable, 120 V compatibility for straightforward installation in non-dimmable fixtures.
  • Feit reliability: a trusted option that combines consistent performance with broad fixture compatibility.

Ideal use cases

  • Office troffers and ceiling-mounted fixtures in commercial environments
  • Retail counters, display cases, and showroom lighting
  • Workshops, garages, and utility rooms that require bright, dependable task lighting
  • Residential PL fixtures in kitchens, basements, or craft areas where clear illumination is valued

Installation and practical tips

Before swapping in this bulb, ensure your fixture accepts a GX24q-4 base and that the lamppost is designed for CFL operation at 120 V. This bulb is non-dimmable, so pairing it with a dimmer will not change brightness. For best performance, install in a fixture compatible with CFLs and allow a moment for full brightness after initial switch-on. Because of its frosted finish, expect even illumination with softer shadows, which helps reduce glare in busy work environments.

Why this Feit CFL stands out from older lighting

Compared with traditional incandescent options, this Feit PL CFL bulb delivers substantially more lumens per watt, a longer practical life, and a cooler, more comfortable color temperature that aligns with modern workspaces. While LEDs offer ongoing energy savings, this PL CFL solution provides an economical, reliable alternative for fixtures already configured for GX24q-4 bases, delivering strong performance without the need for major fixture upgrades.

Choose Feit for dependable, consistent lighting that keeps commercial and residential spaces looking bright, productive, and welcoming.
