A method of feeding a fluorescent lamp, wherein the actual power through the lamp is measured, an actual power value is determined by means of a moving weighted average of a series of most recently measured actual power values, wherein a measured actual power value is substituted with an alternative value if said measured value exceeds a predetermined maximum difference with respect to said average value, and wherein said measured actual power value is compared with a target value, and the power through the lamp is adjusted in the case of a significant difference.
