To escape, bad light and gate eight to nine month!

Advertised as equivalent to 120W halogen bulbs for 15W consumption, they actually only half light bulbs of 50W that they had to replace! This is very insufficient compared to what is advertised.
In terms of "Warm White" was a kind of green-yellow white, cool white probably a poorly camouflaged ... In short, really disappointing about the rendering!
Now, if they meet their low power consumption (15W 4 *, it is more environmentally friendly than 4 * 50W), it's a good point!
There is still some way to go on this type of lighting ...

Edit my review after nine months of use: over the last three weeks, there are four bulbs that have dropped me. Very poor, simply !!!
