Customer Reviews Summary

I bought this Akynite GR10q 4-pin bulb to replace an my bathroom fitting, and it has worked perfectly. The installation was straightforward — the pins lined up cleanly and the bulb clicked into place without needing to force it.The 3500K warm white tone is exactly what I wanted. It gives off a soft, natural light that’s warm without being yellow, which makes the room feel comfortable but still bright enough for everyday tasks. It’s a noticeable upgrade from the faded, slightly flickery bulb I replaced.Brightness is strong for a 16W tube. It lights the room evenly with no dark patches, and there’s no buzzing or flickering when it turns on. It also reaches full brightness quickly, unlike some older compact fluorescent bulbs.Build quality seems solid too. The tube feels sturdy and not flimsy, and it sits securely in the fitting. If it lasts as long as advertised, it’s great value for the price.If you need a GR10q 4-pin replacement bulb and want something reliable that gives a clean warm-white light, this is an easy recommendation.
