I noticed that Nitecore now has a look alike to the skyray 4x 18650 model at 7x the price. So I figured for $20 getting a skyray 3 emitter model was a no brainer.I REALLY like the side mounted switch, 2 modes( I cannot abide 5 mode lights and rear switch models) glass lens, optional long press flashing mode and the perfectly finished gold anodized heavily heat sinked body. On low mode it doesn't even get warm to the touch, after several minutes runtime. To me it's one great deal, and one I can afford to put in the car, motorcycle, and nightstand. That said, I'm wondering about the 7,8,9 and 10 emitter models. I know it won't run as cool or as long but I want to know if anyone else has the brighter models and get their opinion of them.Oh, my one nit about it is from off to on it goes to high AND then low before shutting it off, no option to stay high and go off then to low on the next press to off.
