Light output measurements
For me that isn't the worst. Most manufacturers used to give LED datasheet based values, but since LED output values have been published by people with proper measuring equipment, this should have gone away long ago. Lupine for example since quite a while measures (and their published values now confirm what was measured by various people before that). Philips said about the LBL (website + packaging of the LBL) that it produces at least 270 lumen, and it does. I think they were one of the first to not give BS values but measured values.
It's not really necessary to measure a lamp for a close estimate: Just take the measurements of a given LED at the given current, deduct 10%-15% optical losses and you are fairly close to the real output (assuming no heat dissipation problems)
Btw., I noticed Supernova have removed the main graphic that said places 1+2 in the test in 'Tour' go to Supernova... It's still in the news section though.
What's the worst thing about them is simply the way they act. How they dealt with StVZO approval delays, unavailability, etc., and their (well this Gregor's) derogatory comments about other lamps etc. They are simply not cool (and that's putting it friendly).
And the values they quote for their dynamo lamps are even worse because the current isn't what it must be to even achieve datasheet level values they give, and then, the XP-E isn't in the datasheet at 305 lm, you have to drive it at more than what Cree says you should do (1A), but of course, Supernova does no such thing, it's driven comfortably below 1A.
swhs,
It really is a shame that SuperNova is exaggerating their stats so much that they completely destroy their credibility.
