// Regular update posts in this blog, search on "heat balls".
At time of this edit, last update February 2012 //
Update for December 2011:
They have for the last months been considering an appeal in a higher court and how to go about it.
Meanwhile, in September they tried to have the Heatballs sold in Switzerland (outside the EU) but in October this got a definite no from the Energy ministry official responsible for Energy Efficiency legislation.
Update 27 July:
As expected, the decision yesterday (26th July) was that the "heat balls" can not be allowed, in also being a source of light as banned by specifications throughout the European Union (the name "heat balls", also using English in Germany, was presumably to take away from the light "bulb" idea).
The case was not altogether clear however: So-called "rough service lamps" as used in mines and other such locations are also incandescent lighting albeit not originally meant for ordinary consumers, and there are other exemptions as for small refrigerator lamps and the like.
The issue therefore turns around lighting used as GLS (general service lighting) in ordinary ceiling fittings etc.
The prospect of, in practice, identical general service lighting being continued was obviously too much: there might have been (= might be) more chance of success if the light bulbs had a specific screw-in fitting for a lamp with say a reflector in it to "beam the heat".
Of course, enterprising (and determined) people would then put such fittings also in other lamps, but that is another matter...
June 28 original post
Siegfried Rotthäuser and friends in Germany have imaginatively tried to get round the European ban on regular simple incandescent bulbs by marketing them as "Heat Balls" (more).
This is a sop to the frequent ban defence relating to the fact that incandescent light bulbs give out over 90% of their electrical energy they use as heat (nevertheless being much easier to manufacture, when great brightness is required, compared to CFLs or, even more so, compared to LEDs).
The case has gone to the courts for decision, expected 26 July 2011, see announcement (pdf, in German)
Interesting legal argumentation might be expected in court...
a heat ball or rather "heat bulb" market idea to be followed in the USA and elsewhere?
As for light bulb heat "waste", it is often conveniently forgotten that CFLs and LEDs also convert most of their energy use to heat, although the heat is internalized more - in the case of CFLs leading to a recognized fire risk.
