For example the lux would be different for a 12 degree spot than for a 24 degree flood (halogen). LED would be different too.
Here's information on the lux of MR16 bulbs at nominal voltage for comparison. For a 20 W MR16 at 12V the lux at 30 cm (12") is 20,600. For a 35W MR16, the lux is 33,500. The 35W MR16 at 12V puts out a little less light then a 20W MR16 at 14.4V. However those numbers are for 38 degree bulbs which is a very wide angle flood. Narrow spots (12 degrees) would have more lumens per square meter but would cover less area.
Thank you for your help. I had a friend give me this 17 Lux version of the same light.
I use it in the day time. Has a 6 hr bright run time, 8 hr low run time.
Is easy to recharge and people tell me
That Light is Bright.
Here is the 17 Lux at Night. The car just happened to come down the street when I was taking the pic.
