The present invention relates to an improved UV-LED lamp that can be used for curing pf a UV-curable material. The UV-LED lamp of the present invention comprise a fluid based cooling system, configured for cooling UV-LEDs (3) on the UV-LED lamp, when the UV-LED lamp is in use. The temperature of the UV-LEDs is regulated by a control system (13), adapted to control the temperature and/or the flow rate of a cooling fluid cooling the UV-LEDs, based on inputs from internal temperature sensor (12) as well as information on the temperature and humidity of the surroundings. The control system (13) is configured such that the temperature of the UV-LEDs (3) is kept above the dew point and below a predetermined threshold value. Thereby, the present invention provides a UV-LED lamp with an increased lifespan, as both overheating of and dew forming on the UV-LEDs are avoided.
