Sumber lampu hitam dapat berupa lampu uap merkuri, dioda pemancar cahaya (LED), laser, lampu pijar atau lampu fluoresen yang dirancang khusus. Dalam bidang kedokteran, forensik, dan beberapa bidang ilmiah lainnya, sumber cahaya semacam itu disebut sebagai lampu Wood, dinamai sesuai nama Robert Williams Wood, yang menemukan filter UV kaca Wood yang asli.
