For convenient connection to the drivers listed below and on the LED Drivers tab, the LED ring light has a connection cable with an M8 connector; see the Pin Diagram tab for the M8 connector pin information. This LED ring light also features an EEPROM chip which stores information about the LED (e.g., current limit, forward voltage). When controlled by a Thorlabs UPLED, DC40, or DC2200 LED driver, this data can be used to implement smart safety features.

The sun's radiation is not the only thing that damages your eyes. Sand, snow, dust, and wind can also put your eyes at additional risk. However, a pair of UV-protected shades can minimize the risk to a great extent.

The diagram to the right shows the male connector of the LEDRW40 Ring Light. It is a standard M8 x 1 sensor circular connector. Pins 1 and 2 are the connection to the LED. Pin 3 and 4 are used for the internal EEPROM. If using an LED driver that was not purchased from Thorlabs, be careful that the appropriate connections are made to Pin 1 and Pin 2 and that you do not attempt to drive the LED through the EEPROM pins.

White Light LEDsThis illuminator is a daylight white LED ring featuring a broad spectrum that spans several hundred nanometers; see the table to the right for a typical output spectrum. It has a correlated color temperature 5500 K, which indicates that the color appearance is similar to a black body radiator at the same temperature. In general, warm white LEDs offer a spectrum similar to a tungsten source, while cold white LEDs have a stronger blue component to the spectrum; daylight white LEDs provide a more even illumination spectrum over the visible range than warm white or cold white LEDs.

Polarized sunglasses enhance your vision but do not provide UV protection. They are available in a unique film coating that reduces glare. They allow you unobstructed vision by filtering the light that reaches your eyes. But to know which is better for your eyesight, you must consult an optometrist.

As a tropical country that receives a lot of sunlight, it is a boon for you to get plenty of Vitamin D, but it has its own set of drawbacks that puts your eyes and skin at risk.
