Just started a new venture; subsurface engraving(2D pictures to 3D images inside of K9 glass) For display required putting my cystals on a lighted surface and this really fit the bill! In fact the light was way too bright for my purpose but was able to tone it down by minimizing the amount of light with black masking tape. Now it is perfect for my application. I thought the unit was priced very well. Communication with seller was top notch. Would buy again.
