Brand new compact fluorescent lamp (CFL) in a 2D butterfly shape. Available in 16W, 28W, and 38W options — all with a warm white glow around 3000–3500K. Uses a 4-pin GR10q base, typical for ceiling fixtures, task lights, or some commercial settings. Frosted finish helps reduce glare. Lifespan is rated between 15,000 to 19,999 hours, so you won't be changing it often. Unbranded but reliable. If you're replacing an old fluorescent tube or upgrading to longer-lasting lighting, this bulb's a solid pick. Just make sure your fixture matches the pin setup before ordering.
