First all,

It's nice to see some fresh approaches on making aspharic throwers!

This reminds me of my Franken Mag Jr, where I first used the 66mm DX lens with R2 & got ~150K lux @ 1 meter: http://www.candlepowerforums.com/vb/showthread.php?288704-Mag-Dragon-Jr.-150-000Lux-compact-super-thrower-Lighthouse-beam-shot-vs.-35W-HID

Can I assume you used the DX 66mm lens with R2 on the TRA-66? The DX 66 is a great lens for the money. Where did you get the Switch section of the flashlight? Did you make it?

I would suggest measuring 10 meter lux for your lux@1meter conversion.
For the Aspheric set-up >100K lux, the beam might not have been matured at shorter distances which will affect lux readings.

Also, would be helpful if you share on what lux meters you used & if there's any corrections applied to the readings.

Your numbers are exactly what I would expect with such set-up, well done :thumbsup:

Thank ma_sha1 , I read your threads too ^_^

Yes, They are 66mm lens , XR-E R2 and lux meter from DX, Forward click switch only avaiable in my country, handle 125 V 3A and 12V 5A+.

For 10 meters lux readings I will measure it for next time.



By the way when I set focus for 4 meters lux@1 meter about 160,000 - 170,000 , for infinity focus lux@1meter about 130,000 - 150,000.

My Alu heatsink base It can focusable ^_^

Nicely built! I'm curious how did you adjust the focal point when installing the aspheric lens in it?

How is the quality of the aspheric lens and where did you buy it from?
