PROS (+) Positive point of this bulb
1) Good light patter, Low Beam cut-off is same as Halogen ( will not create glare in low beam)
2) The Fan and Heat sink are compact ( Fits in the place of philips zes fan less bulb)
3) Nice Built Quality.Most of the part are made up of Metal
4) The Low beam Light pattern is Wide, covers good area of the road.
5) Low noise from the fan, when compared to other bulbs
CONS (-) Negative point of this bulb
1) HIGH BEAM light should be little bit in higher angle, This is due to the design fault, Both chips are place in same level. The high beam chips should be placed below the Low beam about 1 or 2 mm. If placed below it will creat HIGHER angle of reflection on ROAD.
2) The heat-sink sits on the clip, but it is not a issue.
