Lumens vs Watts: How to Compare LED Bulbs Before You Buy
Matching the wattage of an old bulb no longer tells you how bright an LED will be. This guide shows what to compare instead, using real bulbs from our range: a 4W filament that gives 400 lumens and a 9W opal that gives 810. It also covers colour temperature, checking a bulb’s base and size, dimming, and why bulbs can’t be returned, so you order the right one first time.
