Great LED lamp, be careful with the dimmer.

The LED lamp is great,
and I had the same room, in direct comparison, 10 Philips LED 6W reflector lamps with 4000K
you will notice a distinct difference in color at that lamp with 2700K color reproduction
is halogen lamp at 2700K almost as in a conventional 35W.
4000K are definitely "cool white".

Therefore, I have now (almost) all lamps replaced by this.

But a word of advice:
I had after I have used all the lights, a constant flickering of the lamps.

One should make sure that the dimmer used a very low minimum load has (approximately 20W at eg 4x6W series-halogen lamps), as failing to achieve the minimum load may be noticed as flickering or noise during dimming.

So I have a lamp, the lamps connected in series, left with a conventional 35W halogen bulb
and had to reach the minimum load my dimmer (50W with me = 4 x 6 watt LEDs + 1 x 35W halogen = 59 watts)
no flickering.

So by the remaining halogen lamp I have a direct comparison of LED and halogen in the color reproduction
and you hardly notice a difference.
