the diverging lens of Tiara A1 provides a very homogeneous light. It is for working and reading much better suited than lamps with light "Throw" and lesser "spill" (you'll forgive the Anglicisms). The lamp is processed with value and easy to use. They can be turned both to the last set level of brightness, as well as having the lowest. Since the tiara can also be powered with AA alkaline batteries, NiMH batteries and with L91 lithium batteries, it is universal, such as emergency lighting, etc. used in freezing.
