For product photography

I bought this Baustrahler times at Lidl of the brand Powerfix, but for a lower price. However, this one seems to be identical. As illumination for construction of these radiators is really too dark. Since it is better to resort to a reasonable halogen spotlights.

However, I use the spotlight mainly for illuminating small objects against a white background, such as product photos on ebay, etc
Advantage is that the built-in energy-saving lamps, a light color of 5000K about which comes very close to daylight. In addition, you can place the spotlight relatively close to the object without the fear must be that this melts away by the heat radiation of normal bulbs. ;)
In addition, the bulbs can be switched individually so you can adjust the intensity of illumination in a limited extent.
