well i finally did it. as i mentioned a month or two ago i felt as good as this light is, it could be much better with the r5s.



this is my first real review with pictures and everything so please be gentle. im now realizeing how much time energy work and mostly a lot of time to do this is.



when i took this light out on a mountainious night walk with friends for a couple hours i found out how great it is for lighting up an area 20 feet in front of you about 40 feet wide.



remember this is a flood light even though it will throw 800ft. so now i have my new 29 palms night walking light, so i dont step on the sidewinders.



it seems from what people were saying on high the original ssc-u2 leds were useing around 800ma per led. i cant remember but i did a current check that i think was 1.9 amps with new fresh batterys. the batterys 3 were in series for 12 volts so some where around 6amps for 8oo ma per led. if someone has this light now maybe you can chime in on what its useing on low and high.



i dont believe this review should go in the budget section because, this light is over 100$, it is very well built, very heavy and solid. and i like the rear twist in switch as it is 100% reliable and if you choose to soup it up the switch wont burn up. the paint is flat black and its terible. the paint is my only complaint and i wished it could be a little lighter. but dureing the walk the weight never bothered me. it also never had gotten hot on high, just a good warm.



ok on to the good stuff, the before and after leds and pictures. REMEMBER THE STRENGTHS OF THIS LIGHT ARE TO FLOOD THE SUROUNDING AREA AND FORGROUND WITH LIGHT. NOT JUST THE THROW BRIGHTNESS. SO LOOK MORE AT THE SIDES OF LIGHT RATHER THAN JUST THE HOUSE OR TREE, THE HOUSE AND TREE ARE MAINLY TO TELL THE DIFFERENCE BETWEEN THE BRIGHTNESS BETWEEN THE OLD AND NEW LEDS AT THE GIVEN AMP RATEING.



as you will notice the pictures with the original leds were taken in the rain, but at the close distance as far a brightness is concerned shouldnt make any difference.





this is low on house with ssc-u2 leds

high on trees u2s the rain drops came out pretty cool on this one.

now for the xpg-r5s, i tried to measure the exact ma to each ssc-u2 led and didnt even short anything out but the driver did not respond. so here is my experimentation with all leds in parallel and direct drive off battery. which probally isnt much different than on high as the amperage slowly dropped also while running.





about 3-4amps, the light had allready run about 1 hour in testing

here are some pictures of the different parts of the light internals.





original high voltage driver, the 7 leds were in series

the new r5s on a 16mm mount yelling at me to give them the juice so they can shine like the heavens! very hard to make everything work centering 7 leds and glueing and they sit on a seperate plate of aluminum.

rear side of driver, i had to grind off all the circutry so as not to have any stray currents or shorts. didnt matter wasnt working anyway.

since my circuit board failed, i found out with 3 batterys in parallel it makes a pretty good difference what resistance batterys i use for my load. the blue 2400 ultrafires that i would consider a low resistance battery because when useing with my given loads it puts out more amps. so with these i had about

7amps that dropped a amp in 15 min. and then started settleing out at a slow drop in amps and volts.





my camera settings must have changed because my 4amp shot of the tree with the r5s looked all muddied. so when i get my new batteries and put my light back together i will retake the tree shot with a given amp rateing.



according to the battery rundown graphs people have been nice enough to make, it makes my choice a little easyier.



originally to me the light was too low on low mode and high was a little bright but ok. but only 1 hr runtime. now it looks like 3-4amps will be my target for about a 2 hour runtime and plenty of light with no losses from digital circuits or resistors.



so the 2 batterys i thinks will be the best are the ultrafire 3000mah and the 2600 tenergy. i have some uf3000 and they work good for what they are designed for. thier discharge rateing is only a c .5 = 1.5amps. this is probally why they are leaking when people are runing them at 2-3amps. these are higher resistance ( will make my light running direct drive to be an amp or so less at the start of the cycle than my blue 2400 ultrafires starting a 7 amps. but im going for the tenergy as they seem to have more respected testing processes and can be discharged at a c 1.5 rate=3900ma. if my light is too bright with the tenergys and i still want to keep it direct driven i will order some new ultrafire 3000mah to keep them matched as they run in parallel.



well, was it worth it? an extra 50some dollars in leds about 8 hrs in building and testing. if im going to use it as my dedicated night walker which i will yes, if it might end up sitting on the shelf with the other collection and get used rarley no, leave it stock. i hope you liked my first picture (real) review. randy.
