In a repeat of the extensive product descriptions I renounce. Those who want to read more technical details, which was recommended the Wikipedia article "MR16".
The Flood Beam has a brightness of 260lm, 310lm cutting edge design. The different luminosity with the same input power results mE from the fact that the flood beam angle scatters a little more. Thus the emitted light is distributed to more space, and that's what makes the reduced luminosity from.
Some technical details can be found only on the cartons of lamps - such as the brilliant statement "4 kWh / 1000h". If you shorten the says nothing more than the "4W" - and that is already the input indication. I have already contacted Lighting EVER, so refrain from nonsense. In addition, a light-temperature scale is shown, where the 50W spotlight significantly further in "warm white" is as the 40W-scattered light specimen. Both are given as 3000 ° K. And "felt" Both claims are false!
You'll also find that the cutting edge design 12V AC (= alternating) needed during the "flare" with 6-17V is satisfied. Whether this really corresponds to the facts, we have to wait until Lighting EVER answered me. Testing I could not because my laboratory power supply is being replaced.
In our household halogen lamps are not very common, but I was being an ensemble of five 20W lamps, where I was able to replace 2 lamps for testing. The course does not meet the 40 or 50W to be compared, are but a good picture. Both "Lighting EVER" deliver - felt - more than twice the brightness of 20W halogen lamps and are so bright that a direct look into it very quickly becomes extremely unpleasant. The light is warm white in both cases! That surprises me, because the two copies of 220V Lighting EVER in our household are at most - of the "cold" side - on the edge to warm white.
Both lamps have a diffuser that diffuses a more, the other less intense. To the lens are arranged around vents in a white plastic frame. As a "stylistic device" looks the little cheap, but a mirrored "normal" halogen lamp - as design agent - also not for everyone.
The prices I find totally "next". Only a crossed out price is specified, which is never to achieve in the market, and on the next line appears reduced by more than 50%. Since you should still call the same the right price, complications can spare at Amazon Search and angry no takers!
All other LED lamps, which I have been in use, the "China man" around the corner - so cheap - and all flickering! All "Lighting EVER" do not flicker - as befits decent lamps!
Long-term experiences have understandably not because I have to rely on the manufacturer's instructions. If anything unusual should happen, I will report here of course. And you wish me well, because the first is supposed to give up their mind until I have reached the age of 90!
Conclusion:
If you get something for free, one is easily inclined to rate the product to positive. However, I think both pears have earned 5 stars. Because both lamps - almost - are identical, I consider the scattered light for more universal version, but where light intensity is called for "on the spot" is the cutting edge design first choice. If you find this review "not helpful", please leave a comment what you do not like rather than simply abzuklicken. This helps me and - especially - other interested parties!
