I have upgraded my headlight to HID from here,
http://www.delonixradar.com.au/hid-xenon/motorcycle-hid-lights/h4-hi-lo/, have 2x3000 cree lights and 2x Hella HID spots.
Checked with my Lux meter today at 5 mt high is 3400, with cree is 4600 and with all on is 7200.
For those who don't know 1 lux is the measurement of 1 lumen per square meter, e.g. a lux of 1,000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1,000 lux. However, the same 1,000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.
With our lights we are looking at a very narrow spread.
