very good quality spots: I have taken 7 W for a bathroom; perfect integration (drill 86 mm mini, 90 is better). the retaining springs are very powerful, perhaps too for easy removal. delivery is not very fast in my case. it does not matter, I'm work and can wait. However what is more troublesome is that two of the transformers unleashed. I found the cause of the fault and repaired for one (micro welding output son badly made and too fragile son). for the other no possible remedy, it is a component that has blown, but which one? gold contacted about it, the seller never responded (2 letters in French and English) as a precaution I cast resin transformer in each for the son no longer pose a problem. So beautiful spots: powerful and gentle light; finishing and perfect integration, reasonable price, but bad seller (in my case)
