Firstly this test is not to slate any products, it has been done to advise you on your next possible purchase with giving you a local perspective. My findings are just that, my findings. The people present with the test will concure. Lights on test with Pricing BrighterLights Solo 620 R3700 (BL) Magicshine R1400 (MS) AyUp Double Lightset R3999 (AU) Pricing gets less the more units you buy from all suppliers Quality The BL and AU have the best alround quality. The MS is let down by its battery and cheap quality pouch but it works although is not so waterproof. Technology The BL wins hands down as it is over engineered, it can be programmed for higher outputs or longer runtimes. The AU follows second with the MS last. Warranties BL = 2yrs MS = 3 months AU = 10yrs Please if I have this wrong correct me. Runtimes on high BL = 6hrs MS = 3hrs AU = 3hrs to 6hrs depending on battery used Beamshots Test 1 MS http://i160.photobucket.com/albums/t169/rad006/MS.jpg Test 2 BL http://i160.photobucket.com/albums/t169/rad006/BL.jpg Test 3 AU with only 1 light (Comes 2 in a set) http://i160.photobucket.com/albums/t169/rad006/AU1.jpg Test 4 AU with one light on head and other on bars http://i160.photobucket.com/albums/t169/rad006/AU2H.jpg Test 5 AU with both lights on bars http://i160.photobucket.com/albums/t169/rad006/AU2B.jpg My camera was set on auto with no flash and was the same for all Beamshots Verdict The MS won hands down with brightness and price although quality can be a factor as its a cheap Chinese knockoff. The BL is a very well engineered light although it is bulky compared to the others but can be upgradable as future technology improves. The AU was the most compact and simplist to use. The split light feature works great to give you a bigger beam. The mountings supplied work well but takes time to setup compared to the other 2. So if money is a factor and you dont mind quality MS is the way to go. If you want something that will last forever go BL. If you want the simplist probably most versatile with an excellent warranty go AyUp. Any Questions??? Special Thanks Must go to Sean, William and Dave (Their Real Names) for lending me the lights to do this test before I purchase any of them myself. A thankyou to Johannes for all the insight into his product and to Brad for putting me into contact with Sean. Forgot my Driver Wesley The light im buying Is none from above!!! Just joking. Ive always bought cheap but when it comes to this purchase, I have the resources to go expensive. I want to do this purchase once so, my heart tells me AU but im lucky enough to have a friend that said if we both take a MS now and I dont like mine in a month he will buy it back from me and I can go buy my AyUps. rad0062010-01-28 02:16:49
