RJ,

I think you are the Thomas Edison of our time.  Very very nice.

Mine came yesterday, now to figure it out! ;D

RJ,

Do they have you on alert just in case Ike turns and pulls a Charlie?

I know that you are the prepared type but if you need anything give a shout out.

Great Job RJ!

I like the Line up.  And as always your thinking of the hardware that is already out, and how to keep it from being outdated.  As to the name Express, that seems apt, considering that your plane is an Express isn't it?

Shawn ;D

grages > This is Tremendous news!  Thanks but lets hold off too much excitement until a little more testing is done. There could still be bumps in the road on it.


I always expect bumps in the road, but I can't help but get excited.

It's packed upstairs in the garage. I will get the info as soon as I have a chance to dig it out.

Not a super rush, but since we don't have a better choice on light engines the only option is to improve the light output reflected.  I have a rough design for a parabolic reflector and I need the actual inside diameter and the approx length of the tube.  I have all of the calculations in a spread sheet.  Here is the rub because of the placement of the led elements on the engine they really are not a point light source, this makes the focal point an approximation, meaning not a perfect parallel reflection will be produced.

RJ,

What is the inside diameter of the Tube used for RoboLight? And the length of the tube, also.

I didn't contribute for that reason anyway.   :)

I wasn't trying to say that you hadn't.  I think at this point that you have the best light source.  With that light engine the only choice is to add a reflector to narrow the beam.  That is what the one I indicated does, takes the beam from about a 130 degrees to 25 degrees total angle.  But the size will not fit into what I remember the tube robo has in it.  The literature indicates you can leave the lens off but again it doesn't matter as the size does not work.  I have looked at alot of LED light engine data sheets and I see no better option than the one you have chosen.

Actually the reflector does most of the focusing in a flashlight.  And the LE (light Engine) does have one designed for it.




This chart is from the data sheet and shows the light output for the bare light engine.


This chart has the augmented light output using the reflector. As you can see the output is nearly 4 times the unmodified engine.


Shows how they are measuring the the light


A drawing of the reflector, only problem is the size, 4.5 inches in diameter

I know at one point that RJ talked about a lens but I don't know if he was able to get an optimal one.  Additionally I would think a reflector would be a good idea, but the one time I saw robo I was distracted to much to look at those details.
