SgtPepperoni New Member 8 Member For: 6y 7m Posted 11/04/18 12:16 AM Share Posted 11/04/18 12:16 AM Ok sorry let me clarify and tell me if I'm wrong please: MK1 has got low/high beam H4 and high beam H1 MK2 has got low beam H7 and high beam H1 Now... according with the specs, the MK2 has better focus because of the lens on the low beam BUT using the high beam you are using only the H1 in the MK2. In the MK1 you are using BOTH H4 and H1. Results IMO theoretically: MK1 better high beam, light from H4 is spread around making you see the environment quite good MK2 better low beam because the lens focus on the depth of the road increasing also the brightness, less spread and good high beam (but less than the MK1) Am I missing something...? I'm talking just theoretically because I don't have instruments to measure the spread of the light (except the visual check) and the brightness of the light. When I was talking about lumens, I was referring to Eg: H4 3500 lumens (bulb) H7 3500 lumens (bulb) With the right instrument you are able to measure if in front of the car you still have that amount of lumens or in case of the lens an higher value because of the focus. If I'm not clear enough please let me know I'm trying my best ? Link to comment Share on other sites More sharing options...

All FG's high beams are H7's. The low beam in the reflector style headlights (FG mk1) have a H4 dual filament globe, which means the second filament is active when the high beams are selected by pushing the stalk forward. Both filaments are active if you pull and hold the stalk backwards. The low beam in the projector style headlights (FG mk2) have a H7 single filament globe (the same physical globe as the high beam globe, coincidentally), meaning it's inactive when the high beams are selected by pushing the stalk forward. It remains active if you pull and hold the stalk backwards. The lumen output is not measured and is unnecessary to do so as the light on the ground is enough to indicate illumination capacity of the system and the globe and electrical system itself actually provides the light output, not the focusing/spreading system. The light spread is as in my post above for reflector/projector style. Link to comment Share on other sites More sharing options...
SgtPepperoni New Member 8 Member For: 6y 7m Posted 13/04/18 12:13 AM Share Posted 13/04/18 12:13 AM I thought high beams were H1 but as you said they are H7, sorry about that. Considering everything you said, would you agree with me that mk1 produce more light than mk2? Link to comment Share on other sites More sharing options...

The mk2 light spread is cleaner and "nicer to look at" and the mk1 looks better from an external point of view (as I have the opinion that projector lensing looks bad when sat next to the reflector high-beam) but has a less "nice" looking light spread.

SgtPepperoni New Member 8 Member For: 6y 7m Posted 13/04/18 12:29 AM Share Posted 13/04/18 12:29 AM How is possible they have the same output? The MK1 in high beam (stalk pushed forward) can count on the H4 (second filament) + H7 high beam The MK2 only on the H7 high beam while the other H7 is doing only low beam Link to comment Share on other sites More sharing options...

I'm talking about the 99+% use case, which is low-beam only. I'm not considering high beams as they're the same in both cases. Link to comment Share on other sites More sharing options...
SgtPepperoni New Member 8 Member For: 6y 7m Posted 13/04/18 04:15 AM Share Posted 13/04/18 04:15 AM Yeah exactly, considering the 99% of cases when you push the stalk forward, (without considering the high beams) in the MK1 you have light coming from the 2nd filament of the H4 (switching off the 1st filament which is providing low beam light), but in the MK2 you have nothing... do you know what I mean?
