VB-16 Cree XR-E Focussable Aspheric Lens Mod Added long throw & comparison beam shots
Take the aspheric lens out of one of these : http://lightfuture.en.alibaba.com/offerdetail/53151907/Sell_LED_5W_MR16.html
one of these : http://www.cutter.com.au/proddetail.php?prod=cut651 on a star base
and put them into one of these : http://www.cones-stuff.co.uk/VB-16 3W.htm
and you get this:
I busted my VB-16
( a new one is in the post ) while "modding it" so unfortunately no electronics and no heatsink, but i used the empty shell of the light to see if my thoughts were right. i had to make a new HS for this test. everything was done in a hurry so nothing is refined here, you have been warned.
Enjoy
Wide focus ( head screwed all the way in )
Narrow focus ( head unscrewed just until the o-ring is slightly showing )
the hole in the reflector retaining ring had to be widened as it covered part of the lens.
As i have no electronics i cannot tell if the VB-16 electronics will work well with the XR-E but i don't see why they should not, but i will know when i recieve my new VB-16. at the moment i am DDing the XR-E from a run down 18650.
I'm really happy with this as i will have a very bright, dimmable, focussable, efficient, long running, tough, small light, with a lot of throw and a nice smooth flood beam in one very affordable package. everything i will ever need
Now to find these aspheric lenses on their own and build a few more of these.........
Here are some comparison shots 3m away from wall using mobile phone camera and not really that blue:
VB-16 Aspheric Left - Golston 7W 2x3.6V right
VB-16 Aspheric Left - Raw NS on high right
Here are some long throw shots from my roof, again using mobile phone camera ( forgive the crappy quality )
i really do not know the distances but im guessing that in the red circle, the beam is split onto two buildings the closest one being lit by the bottom right part of the beam is about 70 meters away and the one behind it is about 100 meters away. it is not very visible how bright the light hitting is in this photo but you can compare to the next photo ( in yellow circle ) when unlit.
in red circle the beam is again split onto two buildings the closest one being lit by the bottom right part of the beam is about 110 meters away and the one behind it is about 180 meters away. again it is not very visible how bright the light hitting is in this photo but you can compare to the photo above ( in yellow circle ) when unlit.
one also has to keep in mind that the area is lit with street lamps so the beam is less visible, this is also evident as the beam is much more visible on the darker bulidings which have less street lights reflected on them.
