I have these G9 LED risen by an "old" LED to replace a 3 spotlights in the kitchen. The reason this lamp to buy was schlcht the design - the old LED just looked bad. Desweitren I had hoped for a better light.
Brightness:
Excellent! Finally, in my opinion classic lamps can be replaced with LEDs. That had never really worked with energy-saving bulbs to 100%. The bulb is really bright - that's what I had expected. With the replacement of only one (3) lamps, I now better light in the kitchen. I want to clear the mention it for the G9 socket really hard is a good lamp to find!
Color temperature:
I would describe the lamp by no means out of warm-white. Warm white is for me the classic pleasant light what one is used to light bulbs (!) - Which to be uncomfortable almost yellowish goes without.
However, this lamp falls in no case into the "cold" range - it is simply know - "brutal" white - but enjoyable.
Here I have very ugly cold LEDs gehabt- but that is already years (!) Ago. The technology is advancing fortunately :-(.
Those who place really worth on a warm white should look for example at the LED's from Samsung, as I have had similar experience.
Dimensions:
Have played with me does not matter. However, there are significantly shorter / smaller lamps. Before buying you should consider what you need. Just as an example: In our dining table and 4 G9 LED's are used, one of which is "too long" because I had to replace a defective short - it looks a little goofy.
Longevity:
I can say nothing -'ve bought the bulb only. For the high price, however, I expect a lot.
Conclusion:
The lamp is anything but cheap - for the price you can also have 2 - 4 No-Name LED lamps for sale - depending on the claim.
However, they sensed my expectation - especially with respect to the G9 base. May she keep long - then it has the 5 star fully deserved.
