Just received this new Clip on light Lamp 2 days ago and WOW!  I had been using the old fashioned fluorescent bulb lamp for the past 14 years wo and problems except the magnification was not very strong and the light — well it was fluorescent!  The Brightech when I opened the box I was just stunned!  It is so high-tech and seems very well made.  It has LED lights in both bright white and the softer off white coloring as well.  Each color has independent dimming capabilities right up on the ring as well as the I|0.  The joints that control the movement of the light positioning use an internal spring system which allows the user to move and reposition the armlamp around wo having to lock individual “joints” in place.  The LED lighted magnifier does have have a spoked wheel which is easy to turn and tighten or loosen.  In a few final words It’s a great lamp!  It’s modern, easy to use easy on the eyes with loads of features and did I mention it’s LED!
