The lamp supports three different types of batteries, 6 AA batteries, widely used Sony batteries NP-FH and nor any Panasonic, I do not know. So best equal for 25 EUR to order a set of 2 batteries and charger. I personally use a charger Digibuddy and buy me for a few euros, the chargers do so. This saves material, cables and clutter. In an emergency, but can always be helped with batteries.
Contrary to other reviews, my model has a slightly recessed power button, which can not be pressed accidentally in your suitcase. Battery is need to load when using certain no wrong idea.
The brightness can be adjusted with buttons plus and minus in many stages, from light to light the lamp size really blindingly bright. Then are currently 4 filters with a diffuser in pure white, and a reddish, bluish and yellowish. Everything you need for effect moods. The light itself is very nice neutral white character and fluoresce only slightly.
The wings, however, are of little use. In the open state, the light is homogeneous and it does not notice that the light source consists of LED rows. Taking the wings on to restrict the cone of light, the LED rows projected to the object to beleichtende. Therefore, the wings are at most to protect the LEDs during transport helpful. Therefore, you can draw on the same for 5 EUR cheaper model without these metal sheets. Especially as the LEDs, unlike incandescent lamps, have a directivity.
When fixing has also been thinking. Included is a hotshoe adapter, so that the light fixture can be sometimes set to the camera and carried on video or pans are used for macro shots, can not tolerate harsh flash. It fits well on flash stand or the supplied mini shoe. Additionally there is an adapter in the delivery, with the flash can be mounted on poles. The fixtures are also sufficiently stable and make a lasting impression durable
Conclusion: Cheaper, smaller headlights with decorative wings, which fits in the camera case. For the right light formation course you have access to significantly more cost intensive products.
