This is Great ! With this I can take advantage of the concentrated beam of the fresnel head on my AD200proii's and use the same mag accessory kit as for the AD100pro. The magnetic round head has too wide a beam for me. I really like the CTO filters. Just pop them on! The diffuser disk seems to round out the shape of the light pattern. You can buy a separate CTO set with an extra mag ring if you want to outfit several lights and not buy the full kit again. I was cutting my own color gels from sheets with a circle cutter but found the magnets are strong enough you can cut out rectangles and sandwich it between two magnetic rings. It works! There are top and bottom rear cooling vents, and so far so good. What a game changer for such a reasonable price !
