GR10q 2D Butterfly Lamp 21–30W Tri-Phosphor

This GR10q 2D fluorescent lamp adopts a butterfly-shaped tube geometry with four-pin base, suited for 220V AC operation. Available in five power ratings — including 21W and 28W within the 21–30W range — it offers flexibility for different fixture configurations. Its tri-phosphor coating ensures high colour rendering and stable white light output. The lamp body incorporates protective rings at each electrode to reduce metal deposition on glass walls, thereby delaying blackening and preserving brightness over time. Rated lifetime is 6000 hours, making it suitable for daily-use environments like offices, corridors and reception areas.
