now I have bought me a zylight Z90, an LED head light where you can change the color temperature and can adjust synonymous effect light.
I made prearange direct Bebob Comparison with a halogen lamp and am a little disappointed. For tungsten halogen clearly beats the LED (the LED in daylight the artificial light;) through the filter.
Here are my questions:
- Are the LED's basically even weaker in the light than halogen lamps? The Zylight is supposed to be the brightest LED, and have failed against the Bebob ...
- The colors have me very confused ... one with the eye seen pink light is seen on the recording as a neutral white (; a fluorescent light with a direct comparison Bebob-Comparison). Why is that please? There can be no one to judge how the color depends on the tape, unless he has continually a monitor it?
- Has anyone else experience with the Zylight and he can tell me?
- What is your opinion, what is better: halogen or LED? And why?
Thanks and greetings
The Iliad

Hello, I wanted to test soon synonymous times the Zylight. It is certainly the most expensive LED head light. Whether it is synonymous the brightest, I doubt that. The statement has been about 2 years ago and since has done a lot.
LED Advantages: Less power consumption, less heat
Benefits halogen, Well still brighter, only one source - that is synonymous only a shadow, constant color temperature, cheaper.
Miut what Halo did you get compared to Zylight? Which Model and how many watts?
We turn now with the Sachtler Reporter lights. Which are normally meant for 75W. We have 100 W in it. Since an LED is unlikely to get close. However, it is synonymous empty after about 20 minutes of great Akkugurt - depending on ambient temperature.
For our construction EX1 VJ synonymous times I wanted to test a LED. As I said, first, the very expensive Zylight. And, as an alternative, the LED16 of bebop ... Let's see whether we will be able to say to the LED.
Where are you from? Otherwise, one could look at the common synonymous times.

What is overlooked always liked the LED discussion:
The color rendering index (; engl. CRI - Color Rendering Index)
... and which is unfortunately in almost all white LEDs underground bad, because it is not a continuous color spectrum. And these poor CRI can therefore not synonymous with correct filters.
Anders says: Where there is a color line in the (; white) light spectrum is missing, I can filter what I want, I'll never be able to create that missing color line.
Therefore, I would (; actually currently (); yet) to invest big in LED technology - it is simply too poor for our purposes. It may make bright, saves energy and is good in handling - but a metrologically correct result you will not achieve that. But the end of the flagpole is in the LED technology is still not achieved long - there will certainly still be done in the near future.

So it is. Our eyes respond quite as simple. Three in their wavelength of laser light as accurately delineated and limited colors, blue, green and red, without any intervening wavelengths appear to us in sum than whites. Unfortunately, not the sensors of our cameras, usually quite clearly visible in conventional "fluorescent lights".

Basically, the difference is little s.Spektrum in the "directedness" of the light, but rather simply. The sum of individual outliers shown in the spectrum synonymous again some white, about 6500 Kelvin at the LED daylight lamp. But I only know it synonymous white. Other colors or frequencies may be seen completely false, as red-green to pink or brown to a faded blue. You can see this on the basis of such a typical LED spectrum quite well: zum Bild
Better lights that have a full spectrum can, at least to some extent how these HMI: zum Bild If you are over all frequencies similar effects to be expected. Ideally, a camera can then record a picture that is so, as one sees with the eye. That is good because the colors pop on all frequencies well. Lamp types differ in terms of the spectrum. Are good spectra, which have no single outlier, but are all well represented. The create a few LEDs. Even with conversion filters you can travel to nothing, they simply limit the range, but of course, add any additional frequencies. Therefore, one can see differences between daylight, artificial daylight, incandescent and LED light. It is less the color temperature but different color effect, since the spectra look very very different.

... of course, explains why I must light pink with a white on the camera to get. I had only checked the advance ...
Unfortunately, there does not help me with the wonderful feature of the color temperature setting is not much.
arrrggghhh, and the bebob lamp would have been so much cheaper ...

Moreover in addition to the poor quality of the unfavorable light color temperature. Who is filming at night with unfiltered LED lighting people, does not make a lot friends. As a victim shall have a light beam to the subjective well-being of a water body, for as we see the same moment from others. While this is similar to white balance the camera out as far as possible, but we still lost the great advantage of a halogen light, the light temperature around 3200 Kelvin significantly reddish-yellow and so is everything on the face which is red (; skin blemishes, skin pores, pimples, etc.) or wegfiltert veiled. With LED light can be seen from the worst case, such as aging Leberkas. Moreover, such an LED light in artificial light has a similar atmosphere as congenial an oncoming car with xenon headlights. I would not let me shoot it. Of course you can use a conversion filter that brings the color temperature to 3200 Kelvin, but then you lose an incredible amount of light output. In addition, the hotspot and the multiple shadows of the LED lamps come. I got myself a sort of Notnagel for 230 euros, the Litepanels Micro. If you go once the battery is running low of halogen lamps. Or as a brightener by day. Or as a hand light hair, etc. Otherwise the thing will remain in the pocket.
