As an amateur photographer I wanted to get a taste in the product photography. A receiving table I already had, only lacked the lamps. Here I have chosen for continuous light, with the hope that the brightness is sufficient. Now the product: The quality is not so great, but it works. The lamps do not last forever in the position that I have set, as the spring is too strong. The clamps are made of plastic, but hold far. I then noticed quickly that I do not come to decent pictures without light shapers. For product photos on Ebay of course, it is sufficient, but if you want to make "artistic" something, then not enough bare bulbs. But you can softbox snoot etc. tinker. The brightness is sufficient, but one can illuminate in product photos of any length. Runs nothing away. :-) If one wants to deal seriously with product photography, then you can not avoid an ordinary lighting, but the multiple costs. The lights are so useful and not cost as much, so 4 stars from me.
