Today I received the first of several SkyLumen Nguyen flashlights I ordered and am very impressed. This is a serious, get the job done, meant to last piece of lighting equipment. No frills design just like some of the highest end camera manufacturers. It can easily be handled and mode levels changed with work gloves on. Vinh should be very proud of this project finally coming to fruition. I'm sure his Dad would be proud of him. I know I am and will be proud to own several of these lights that are the product of a company Vinh and his Dad started years ago. If you can't afford a SkyLumen Nguyen just yet, save up for one, it will be worth it. Might be the last flashlight you will ever need to purchase. It's that good. It's that durable.
