Clever Optics
The Philips Saferide Lumiring has a clever lens which produces a nice uniform glowing ring around the perimeter of the light. This gives it brilliant visibility. Almost forward facing at 320 degrees. The ring is 110mm x 50mm and combined with the even illumination it makes the light very visible and easy to place. In that way it's more like a car light. Watch car tail lights and notice how the intensity is OK up close and intensity doesn't appear to change much as they get further away. This is because of the large even illumination. If you compare that to a high brightness LED light you notice quite a difference. The LED is usually overpowering up close and when turned in the distance very weak. I used to think bright flashy LEDs ruled, the brighter the better, but I've completely changed my mind. Now I say make like a car. I've never had a problem seeing a car with it's lights on....
