A few days ago I ordered the really bright white light designed for the Phantom. Got them today and they were designed to fit the regular Phantom with smaller battery. Did not want to do rigging, so made a trip to Walmart to look a bicycle lights for my Phantom 2 Vision. Found several in the hunting dept. The brightest one was 150 lumens but had three AAA batteries to operate....decided it was too much weight...so went over to the bike department and wow! found the Wo light set...one red one white with a all on or blinking switch. There are about as big around as a quarter and have two of those small flat batteries included. Approx 1" deep and very little weight. Mounted them with the white velcro on the battery where the green bars appear. With the white velcro you can see thru it to check your battery lights. There is no lumens rating but my guess is somewhere around 100. Price for both is only $12.97....Can not fly with the lights today......snow and wind here in VA...but know they will help in orientation for a tiny bit of weight added. Hope this helps. Keep em' flyin'
