The lamp does not even have a (!) Shone operating hour. It is a low-cost and thus a disposable product. Unfortunately I was caught in a moment of weakness, the number of lumens. For Reclamation Story: First me, the seller has not responded and made to stalling tactics. Then I was advised that I could not evidence of the inaccuracy. Finally, the seller has meant he was looking forward to my next purchase. Because I smile now only. Thank never again !!!
