That's extremely cool. 90 Lumens isn't exactly earth-shattering but not bad for the packaging! Should be fairly scale too. I like it!

I think so too...


But, I must add, like I always do, an idea..

wouldn't it be really cool if they could offer sequential patterns and "police" colors...like flashing red, blue and white lights?

[rccardude04]

Yes. It would be.

Make it happen.

90 lumens is a extreme amount of light ..and since its runs off of 12v.. a 555 a few resistor and a cap or two and you can make a flasher.. not like there's no colored polycarbonate on the market for POLICE colored lights

[rccardude04]

Come on TNT... 90 isn't extreme. I have a bicycle headlight that's 1800.

And what exactly is a "555?" I know a few basic electronics can build a flashing circuit but I never looked into it...

90 lumens should give you a 75' of light 1/4 of a football field in USA at 8" off ground I can not be exact as I dont know the beam angle..
sorry its a 552..its a simple flasher with a pot in circuit that can be used as a flasher unit.back in 1976 i built many of these..radio shack has these in the electrical parts drawers in all shops..not sure this system could take that specs are very limited

INFO from Starline..
LED Brightness and Beam Angle
The total brightness of a LED bulb or flashlight is best to be measured in lumens. The common range
is 10 to 1200 lumens. Minimal practical brightness is 10 lumens. 30 lumens are bright enough for most
common uses of a flashlight. The super bright “tactical” flashlights start at 90 lumens. These are good
for lighting up objects at a great distance and are often used by police or the military.
It is important to understand the negative correlation relationship between the beam angle and luminous
intensity (lumens). As the beam angle increases, the lumens can decrease and vice versa. What this
means is that the light from a flashlight with a narrow beam angel will appear more intense as the light
is concentrated over a smaller area. Light from a flashlight with a wider beam angle will appear less
intense as the light is being dispersed over a broader area.

And yet nothing about an integrating sphere? Hmmm.... Lumens is defined by the total output. Has nothing to do with distance or beam angle.
90 lm should be pretty cool on an r/c car, but it's not "extreme" like you said earlier. I bet my old LED set from RAM is 50-60 anyway. Not earth-shattering, but still pretty scale. That's all I was getting at.
In the global scheme of things, 90 might be a decent absolute minimum for a commuter bicycle headlight (if you need to see the road in front of you at low speed). 150 wasn't quite enough for me but we ride fairly quick and like to go to the real MTB trail at night. It's an easy trial, but you still need to see pretty well if you want to accomplish anything.

For the flasher circuit, I'm sure it's easy enough to build! Could always overcomplicate it with an Arduino and change the flash pattern however you want.
