I know we are coming onto summer with all the light evenings for riding but I am doing a night ride shortly and a couple of months ago replaced my "OLD" front lamp that was losing some efficiency and battery life.
I have been a fan of the "USE" Exposure lamps ever since I got my last and first one. That was 7 years ago and it gave out 280 lumens from two x 5watt LED's. Battery life was not that good from the L Ion battery at only 2 hours on full beam but on low power it had 7 hours so would last a road ride. But as I say- it was beginning to go down on me so bought the updated version. Half the weight- double the power and battery life.
Went out for a ride tonight and Full power is blinding. Medium power is suitable for normal riding but the low power is not quite good enough to see fully. It would be fine for Town riding with street lamps and If put on blink will definitely get the attention of other road users. Got home and put the Pinnie 80 ft from where the pics were taken.
That is low power and as I say- not really good enough for riding my country lanes.
I could ride on this and still see enough at speed and they say that the battery should last for 7 hours at this level.
I would hate to come across the full power as this is blinding. 680 lumens and the spread of the beam was pretty good. They state 4 hours light at this level but if I use this for that long- My night ride would have finished and it will be dawn.
Finally- to show the two lamps- the old one is the larger of the two and incidentally the price has gone down by about 25% in the last 7 years. Still expensive but you have to pay for quality if you need it.
