Today I got 2 P4 Bin warm tinted Cree LED's from GB Erasmus :goodjob:
Without wasting any time, I started working on Fenix E1, the only Fenix that opens easily.
1) Removed Old LED + PCB (unsoldered the wires)
2) Chopped Off Cree LED's Corners
3) Cut Circular PCB shaped Plastic disk (from Drinking water bottle cap)
4) (Most time consuming) Filed the reflector untill I could see it almost filled Green/Yellow Phosphor, i could have filed still more, it would have given me more throw... but I wanted a flood type beam
5) Soldered +ve and -ve wires to top of LED put back whole assembly.... and .... there you go
Could you imagine how much powerful it is now? More powerful than Fenix L0P on Lithium!!!
Here are a couple of beam shots
Left is Fenix E1 CE with NiMH Battery right is Fenix L0P with Lithium Battery! ... guess what's brighter of the two...
EV = 0
EV = -1
EV = -2
Did you notice the even beam, Larger & Brighter spot (I am estimating at least 25 lumen's)...
Notice Smooth Transition from Hotspot to Flood & Corona?
Is there any "Dark Ring" :nana:
Did you notice Uniform Hotspot.....
The Fenix E1 Reflector is really deep and is best suited. There is No void, all of the light is reflected front, you can barely see the LED ring. I purposefully didn't file enough (so as to have more throw). I needed more flood kind of beam.
Fenix L0P Reflector is not as deep and is shallow, if you file off a shallow reflector (to focus deeper LED die) you are gonna loose a lot of light as there would be void around the ring of emitter would be much more visible..
How'z that
and NO LED didn't even get warm (I touched the LED base while testing the light in open, it was at ROOM Temperature) so NO heat sinking what so ever required. LED probably is running 90-95 mA (measured by elcheapo meter)
