Does the E28R feature overheat protection?Updated 2 years ago

Yes, it does.

The light will turn down to 900 lumens after the Turbo setting as been active for 1 minute.

The light may accumulate heat while on in the higher output levels. If the light reaches a temperature of 140° F (60° C), the light will step down by 5% every 10 seconds until it reaches 350 lumens. Once the temperature is below this threshold, the light will step up 5% every 10 seconds until it reaches the previously selected brightness level.
