Unlike other lamps of this company is the duration until the lamp reaches its full brightness, perfectly acceptable. In a table lamp used with screen, the light is actually warm. How long the lamp maintains now, can only show the long-term use. In this respect, the review must be superficial in this respect. For the lamp speaks in any case, a 24-month manufacturer's warranty side. Two years to keep in any case the lamp so.
A clear minus of course the use of mercury. Again, the question arises again: harm ordinary light bulbs really the climate? Mercury harms any case indisputable human health and at a non-professional disposal and nature. To what extent this is progress now or whether there just the devil with Beelzebub is expelled, everyone should own one can divorce (which is no longer goes to the EU, the bans are pronounced).
