LED ring lights

A round thing in many sizes

Mini LED ring lights RL1 and RL2

The RL1 and RL2 miniature LED ring lights are ideal for use where space is limited, due to their compact size. Nevertheless, these ring lights provide a lot of light, eg for camera applications or as lighting for production machines. Both series are available with two different nominal working distances, which is achieved by different LED installation angles.

LED ring lights RL4 and RL5

The series RL4 and RL5 are primarily designed as reflected-light illumination for microscopy. The working range of the ring lights is selected so that the focus is at the typical distance of the objective and the stage from standard microscopes. Both series are available with two inner diameters, so that the right model is available for all common microscope types.

Power LED ring light RL12

The RL12 power LED ring light offers enormous brightness thanks to the twelve 3W LEDs and is suitable for applications with increased light requirements, eg in conjunction with high-speed cameras. Thanks to five different variants with different geometries, the perfect lighting is available for both small and large working distances.

LED ring light RL5-88

dimmable LED ring light for microscope objectives up to Ø 88 mm in different light colors

Like all StarLight products, the RL5 is characterized by the highest quality in material and workmanship. Electrical and mechanical components are perfectly matched, which guarantees professional users the best possible light and easy and safe use. The LED ring light RL5 was primarily developed as incident light for microscopy. For this purpose, it can be attached to lenses with a clamping screw or screwed on thanks to the internal thread. In addition, it is possible to adjust the inner diameter by means of reducing rings. The brightness of the RL5-80 can be set between 0% and 100% via a knob on the remote desktop controller. Thanks to the optimized electronics, even with low brightness settings, the result is absolutely flicker-free, homogeneous illumination. Due to this constant lighting conditions, the LED ring lights are also suitable as lighting for photo and video recordings. There are no unwanted stripes on the pictures.
