LED ringlight, dimmable, quadrant control, 144LEDs, 90V-264V
Ringlights are ideal for macro and micro-photography and can provide even and shadowless illumination. The ring is usually clamped around the camera lens or a stereo microscope's objective shroud.
These ringlights are studded with many light-emitting diodes (LED) for uniform, highly efficient, cold light. LEDs have a rated life span of 100,000 hours and the light has daylight colour temperature. When compared side-by-side the OYK-B144T is slightly blue in colour.
The two light sources differ in design but both have the same features. The OYK-L72T has a dial type brightness adjuster whereas the B144T has a push button, step type adjuster. Both offer directional lighting via quadrant control. The diodes can be switched to use one, two, three or four quarters of the ring to achieve some shadowing effects. For stronger shadowing effects, consider a LED fibre light source, detailed lower down this page.
