I had dug myself in advance by the reviews on Amazon and have found among dozens positive Even a negative end. There writes a user that he has purchased the product for installation Spots with clip art and has found that the attachment of the bulbs is not possible.
I have purchased the product for the same purpose and have sadly pointing this user not believed. Due to the very thick bulge at the bottom of the light bulb, it can not be far enough push into the socket, so you can clamp the wire clip for attaching it.
I think the problem for quite solvable, but here is the manufacturer of the lamps in the requirement to produce this transition a little more delicate.
I give the product anyway 3 stars because I am convinced of the matter and technology per se and the LEDs show a beautiful light. I also have a significantly reduced energy consumption (4x 5 watts as opposed to 4x 35 watts). This will make hopefully on the next bill.
I have attached the bulbs eventually with a glue droplets. This is not in the sense of the inventor, but the end justifies the means here with me.
5 star there, if the problem is solved with the clips.
