Replacing my tr-1200

That's right. Or at least it ought to be.

However, some drivers don't scale linearly with voltage and it may use a bit more or less than the predicted value. Above an amp or so the resistance of the meter leads and the internal resistance of the meter also come into play.

Above 10A or so you need to be very careful to get meaningful current readings.

well an update, the one from dinodirect arrived, one week less shipping time than all my DX products!....first i was nervous to open the packaging because i noticed after ordering that it was described as an MC-E light. I opened it thankfully to find the 5 q5 emitters as shown in their photos. I was nervous to try it out. It had the tail cap/clicky that the original tr-1200's had when people still raved about the lights. that was my first note of excitement. i screwed on the extension, popped the batteries in and turned it on....

its bright :D my tr-1200 was no brighter and could throw no further than my skyray sr5. Its daytime here so i cannot do a true night time comparison but so far the hotspot on the new palight is much brighter :D can't wait for night time! Also i dont have a multimeter at the moment but i'll get tailcap readings soon!

Also, dino direct sent me a $10 off coupon for any purchase over $40! not bad at all!, and they also sent a $8 off any purchase over $25! I am pretty impressed with their service thus far!

thanks for the help everyone!

almost forgot to mention, my tr-1200 suffered from flickering in all modes except strobe and high. this new palight works flawlessly in every mode so far!

Beamshots please!

i'll get some up asap, i am gone for the long weekend but once i get back i'll do some. i've never taken beam shots, can anyone instruct me on how they want them done?

Find some obvious feature at a sensible distance - 15-30 metres. Aim at it. Exposure that makes sense - you'll need to experiment with this.

sounds good! i'll compare it to perhaps my skyray sr5, and my aurora ak-p7 2 mode :) when i get the chance of course.

Congratulations on your new replacement. I hope it works out well for you.

Let us know how that light measures out w/ 1 and 2 and all 3 cells. Also, you mentioned modes, but their listing make it seem like 1 mode?

Also, dino direct sent me a $10 off coupon for any purchase over $40! not bad at all!, and they also sent a $8 off any purchase over $25! I am pretty impressed with their service thus far!

Do those coupons stack with their 20% off code? or only one valid at a time?

bad news :( It must have simply been an illusion. I brought the light out to my cabin on the weekend to find that yes, its very bright, however when turning on my skyray sr5, it is still only slightly brighter. not a big difference. I just got home and measured at the tailcap. 1.02A on high on fully charged 18650 :( apparently the 'good' ones were pulling over 2A.

well. I guess i took a risk, but its safe to say this lousy driver has been put into all of these lights, no matter what the branding is on the light.

can anyone suggest a light thats going to be brighter and throw farther than my aurora ak-p7 2 mode and m skyray sr5. im having a hard time finding a light more impressive than my $20 skyray. the aurora is BRIGHT but all flood.

Darn, Im sorry to hear that your new light doesnt put out the lumens. Have you thought about a driver swap to wake it up?

is there a tried and tested driver for this particular application? i am pretty new to this stuff, but open to toying with it! how complicated would it be to take on the task? where could i find a driver?

On that one I think you just bridge one point and replace the stock driver. Only major skill required is soldering.

hmm, if i could get a little more help or instruction, i think i'll definitely order it and give it a shot!

There's two places to solder wires to (+/- to leds, which are likely wired in series). Take off wires from old one (on the led's side), stick on new one :). If you figure out how to use the iron, the rest should be obvious.

The main concern is that the size is correct for your light. Those circles on the back are +/- for the battery. If it's not the right size (that one is 26mm), it may get complicated since the driver pcb depends on mechanical contact to the batteries. If it's the right size (and there's likelyhood it is), buy it and you will figure it out pretty easy.

awesome thanks :D

measured today (finally) and the driver looks to be only 20mm, not 26mm :(

I wonder if you got the right one or did dx send you something else? Does it look like the one in the photo?

oh sorry, i meant the one in the flashlight is 20mm so i dont think the 26 mm will work if i ordered it :(

is the same I have got with my Smallsun 1200L. That is far avay from 1200 lm. I have got a 5xR2 dropin from DX, that's much brighter than the original. Sadly, on the specimen I have got the driver board got fried. I'm wating for the replacement.
