If you know that you want soft, shadowless light for macro work but can't decide whether to go with flash or continuous light, you can have both with the DL-RLF90 LED Continuous and Flash Ring Light from Dot Line. In continuous mode the unit has seven brightness levels with a color temperature of 5600K and a CRI95 rating indicating accurate color reproduction. The ring light is equivalent to a 56W tungsten fixture and Dot Line includes an amber conversion filter if you would prefer to shoot at 3700K. Run time is three hours on four AA batteries. In flash mode the DL-RLF90 has power adjustment of 1/64 to full power and accepts the same amber filter as well as a provided diffuser. Dot Line has got you covered to use almost any lens you might own with the inclusion of 40.5mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72,mm, and 77mm lens adapters.

Dot Line DL-RLF90 Reviews
Same item is cheaper under other brand names
After paying over $100. for the Dot Line branded item, I've shopped around the Internet and see Neewer, Bolt, Lightdow, Piloture, and Banggood labels on what appears to be the same product, often with more plastic parts in the box, in the $30.00 price range. If I had it to do over again, I'd stick with B&H but go with the Neewer RF550D brand that offers a stand and a blue diffuser ring above & beyond what's in the Dot Line box for about 1/3 the price. Not sure what happened to the pic that went with my earlier review. Will try another of a vintage Kodak to show the need for a better diffuser.
Good for experimentation - not a pro setup
I bought this primarily as an experiment to see if it would help in recording some small family artifacts I have. As a budget-priced ring flash, it serves its purpose with a number of limitations. It does NOT provide TTL metering, so you'll have to calculate and experiment to get proper flash exposures, or use the light function for full-time, full ring lighting. It provides light in four modes: Full-time full ring light, Full ring flash, Left side flash, and Right side flash. All modes are intensity adjustable to 7 levels. Likes: Price & a chance to experiment. Dislikes: 1. Plastic adapter rings that screw on the the front of your lens like a filter. Fine for tripod static set-ups, but easily knocked loose if bumped while moving around. 2. LEDs show up as a ring of bright spots in any reflective surfaces. Better diffusers would be nice (comes with clear and amber). 3. Flash unit tends to spin freely on the adapter ring, so sometimes if you're not paying attention left becomes up. 4. Full-time light is full ring and, while adjustable for brightness, cannot be selected for left or right. Bottom line: For a hundred bucks or so, it's OK. I like to experiment and tinker, so will try tucking some extra diffusion material into the diffuser ring and maybe securely glue a metal step-up or step-down ring to the next-sized adapter (ie: step up the 72mm adapter for my lens that takes a 77mm filter) for a more secure attachment to the lens. Pic of phone dial is hand-held with Canon 5D MK-IV with 24-105 f/4 lens on 36mm extension tube, 1/90th at f/4.5, ISO 800 and flash set left side only at +1.5. Note ring reflection around #9 in the dial of the Western Electric 300 series telephone.
