well, they showed up. not bad going, posted in St Louis, Mo, on the 17th, so fair play to both superbright leds and the US postal service.
first impressions not that impressive, IYSWIM - nicely made units but didn't look all that bright. There again, it was a bright sunny morning, so ordinary lights don't look "bright" either - the standard LR fittings aren't the best in the world either. The lenses do a fair job of scattering the narrow LED beam though. I imagine that for fitments with clear nonfaceted covers, you'd do better with the wide-angle type.
few minutes ago, about the sort of time you'd be looking at putting lights on and they look much more impressive. 12-led white ones for the front are impressively bright in the dusk. ditto the 19-led rears in "rear light" mode. Brake light mode is pretty bright.
Indicators not so clever - as expected, they flash too fast. Reasonably bright units however. Sundry playing with various resistors yielded not much of any help. The 6 ohm 50W resistor they supply isn't enough for one side on its own, unsurprisingly. However, it's a) over-rated by at least a factor of 2 for what it's doing and b) over $4 each. A little searching in Maplin's online catalogue produces 6.8 ohm 10W wirewound resistors which say they can stand 10X rated power for 5 seconds, so I reckon they'll handle pretending to be an indicator bulb quite well - it's around about 20W at a
50% duty cycle, but only when the indicators are on. Those are 19p each, and 4 of them including postage are less than one of the big feckers.One thing I tried was a dim-dip resistor, that slows the indicators down but is too low resistance, and makes a voltage drop which makes the light dimmer.
had they looked as though they'd fit, I'd have been tempted by the jumbo-size 30-led ones, but I'm fairly sure they'd not fit in the normal lights.
tried to take some pictures late this afternoon, but they came out crap. I'll have to dig the tripod out.
