Request InfoUNITRON Ltd.COMMACK, N.Y., July 14, 2010 — Unitron Ltd. has introduced the 15854 LED ringlights. Manufactured to fit any stereomicroscope, they are suitable for observing circuit boards, electronics and highly reflective specimens. Designed for the cost-conscious consumer, these light sources offer good value as users transition away from older fluorescent and halogen light sources. Features include 72 LED bulbs with 10-step variable-intensity light control, sectional lighting control that allows users to direct the light from four separate quadrants, a 60.5-mm inner diameter and color temperature of 6400 K.
