Has anybody tried these basic (cheap) "work lights", usually advertized usually as 18 watt CREE? I've got my Hella FF50's mounted for night time use when I actually want the driving lights to help me see, but these LED's might be a way to be seen during the daylight hours. A lot of sellers carry them on Amazon, eBay, etc. for about $20 each (+ or -); almost certainly all just re-branded versions of the same Chinese product. These, or similar, come in both spot and flood patterns and supposedly put out about 900 to 1200 lumens depending on whose ad you read, so similar to a 55w driving or fog light for total lumens , but at 1/2 the cost and 1/3rd the power.
I'm not very hopeful about the LED's being adequate to light up the road, but being bright, glary (?), and white/blue, they hopefully will nicely augment my triangle of light.
