One of the more recent additions to Sunpak's lineup of flashes is the DSLR67 LED ring light, a low-cost, easy-to-use LED ring light for macro work with an SLR. It's simple to use: just turn it on and shoot. Although it won't put out as much light as a traditional strobe ring light, it only costs about $50, less than a strobe ring light. It's meant for when you need to add a little light to small subjects.
The DSLR67 fits most lenses with a filter size up to 67mm. The ring light mount slides into the hot shoe, then you adjust the flexible arm so the ring light aligns at the front of the lens. Its flexible arm allows for almost unlimited movement, even off to the side of center of the lens. It has an effective light coverage distance of 2 inches to 20 inches. The ring light takes three AAA batteries and weighs 4.2 ounces without them.
There are 12 LED lights spaced out around the front of the ring light. The LED lights have a natural, daylight color, with a color temperature of 5500 to 6500 degrees Kelvin for properly balanced photos.
Since the LED lights are on continuously when the ring light is turned on (unlike a strobe flash that only lights when the shutter is pressed), its constant light output allows you to see the effects of the light from the LED ring light before the shot is taken.
