Very good product: installed to a terrace of 50 sqm, at a height of 3 meters .2: Flash (too?) Strong !! For a warm white, I find it a bit cold though, I dare imagined the cool white !! The product must be connected by an external domino to lamp: while the lamp is ip65, but if we do not install what domino in a junction box IP XX, the installation of a lamp IP 65 is useless .. . Conclusion: Very happy with this product. Could be supplied with a junction box and terminal IP 66.
