INTRODUCTION

Our experiment title is ‘effect of UVB on melanogenesis’. Many papers are mention about relation of UVB and pigmentation. So this experiment needs a UVB lamp. Definition of UV is electromagnetic radiation with a wavelength shorter than that of visible light. The part of the electromagnetic spectrum which ultraviolet light covers can be further subdivided in several different overlapping ways. UVA is long wave (400 nm - 320 nm) and black light. UVB is medium wave that Wavelength range in nanometers is 320 nm - 280 nm. Last type of UV is UVC that is short wave (200 nm - 280 nm). But our laboratory didn’t have UV lamp. So, the purpose of this memo is to provide you with my recommendation of 4type UV lamp. The UVB lamp –Model VL-215.M (vilber lourmat) or Model VL-215.LM (vilber lourmat) or model UVB-16 (Ultra-Lum). My recommendation is based on the UVB lamp specification, cost, option and ease of operation.
