|Notes:||It appears that
Osram here is up to something a bit interesting here, selling "light"
rather than lamps. The "Active" and "Relax" lamps are part of
a range of colour temperature corrected lamps available in a variety of
styles. The Relax lamp is a lamp with improved red/yellow
output (actually - it's the blue output that's attenuated).
This means that it's a very warm light, ideal for use in places like
dining rooms or lounge areas where an relaxed mood is
desirable. The Active lamp on the other hand has an
attenuated red output, producing a more neutral white light, idea for
working areas like utility rooms, garages, or for use in desk
lights. I imagine though, due to the attenuation of the red
on the Active lamp, that the efficacy will have taken rather a
pounding, as relatively it will be filtering out rather a lot of light.
Basically speaking, this is simply a slightly more modern version of the old "Warm white" coloured lamps which you used to be able to find anywhere and everywhere. Only real difference here, is that Osram have come up with a new type of powder coating which appears to have a more tightly controlled grain structure, and a consequently higher transmission efficiency. I don't believe it's a huge difference, but as with any incandescent lighting, any efficiency gain is something to be grabbed by the scruff of the neck and put into use!
I cannot actually discern any logical reason for the use of the unusual lamp shape (The DC shape) which Osram chose to use for the Active and Relax lamps. The main one I can see is that it will make it stand out more on the shelves (worked on me!). It's nice to see a bit of variety.
Just the unusual shape makes this a nice one to have in the collection though.
