I am not at all disappointed CG, I had the best Osram bulbs in the headlights I could find and these are vastly better at lighting things up. Being an electrician I'm used to the various types of lamp and colour rendering available now for LEDs, which is getting very good indeed. The thing is LED light is a 'different' light to anything else. I don't know how to describe it but it is different.
To someone running factory headlight units with incandescent bulbs in I would totally recommend these as an overall improvement. To someone running factory headlamp units with HIDs in giving poor beam scatter, I would recommend these to give a very good beam (I have yet to get them checked for alignment at my MOT garage). To someone running replacement headlights designed for HIDs I would say to stick with them as the beam, brightness and colour rendering are superb on purpose designed units with good quality HIDs.
To boil it down, if HIDs in the correct headlamp units are at 10/10 for everything, (edit- except warm up time 5/10) I would give the LEDs 10/10 for ease of fitting, 10/10 for beam cut off, (edit- 10/10 for warm up time) 8.5/10 for distance and 8/10 for colour rendering. I would also say I don't know of anything better without changing the headlamps.
Hope this helps.
