I see what you mean, I guess I've been looking at them and trying them for a few years now so I just many, many differences in the style and types of chips, etc between them that I don't see any standard at all...
As far as those Beamtech, I wouldn't settle for only 49% of stock brightness, that's why I ordered the DWVO non-Philips for only $16.49 plus 15% off from eBay, I'll be reporting back once I get them... I do see how they may be a little too bright and create some glare, so I'll re-aim a little if I have to. Re-aiming is fine when the whole cut-off is raised from overpowering, I just have to hope the glare is not excessive.

The Peak Low Beam Lux column is actually % amount over stock halogen. In the Beamtech case it would be 49% brighter than a stock halogen.
