Okay, due to high interest, I was able to get all the pics loaded up to Imgur. Holy cow, it took over an hour to do it. Maybe paying $400 a year to turn Photobucket back on is not such a bad deal. Lol
My complaint has to do with the folder structure. With Imgur, you can load a bunch of pics into a folder, but the folder has no thumbnail view. If I want to find a certain picture, I open the folder and then have to scroll down a super long page of full sized pics.
With Photobucket, they had thumbnails to easily find the picture I’m looking for.
I’m not sure, but I suspect that Imgur just dumps all your pictures into your account and lets you organize them in folders. You can delete a folder, but the images stay. IDK, it seems weird.
I finally decided to install my new xhp70.2 (P2-1D) cool white emitter. First I had to upgrade the bypass wire in my tail spring as the copper braid kept burning through.
I’m getting 17.3 amps once it stabilizes after 15 to 20 seconds. Pretty impressive using the Liitokala blue cells.
I apparently didn’t do a ceiling bounce measurement after adding the TA Fet driver. Using the stock driver with R100 added gave me 350 lumen in a ceiling bounce, so I know the new driver with old xhp70 would be well above that. This new 70.2 shocked me with a 740 lumen at turn on and about 700 lumen after it started to stabilize after 20 seconds or so. That’s double! If the stock driver with R100 is about 3800 lumen, I’m guessing I’m well over 7,000 lumen now.
The yellow corona is not too bad in this cool white tint. At least not at the higher brightness levels. I can probably get used to it. The 50.2 in 5700K that I tried out was definitely more yellow and I did not like it.
The new 70.2 does have less of a donut hole pattern. It’s not gone completely, but much better than the xhp70.
The first 2 photos below are a direct comparison of the 70 and 70.2 on my L6 with the same reflector height.
.
If I move my reflector away from the emitter just a little, the donut hole reduces more. See below.
Now when you look at these lights without the lower exposure, the donut shapes are much harder to see. The hotspot of the 70.2, which is shimmed out looks really smooth and has sharply defined edges.
Here are the same 3 photos as above, but normal exposure values.
I’ve only had the 70.2 in my light a few days and the batteries are already running down. It seems like I’m getting less than half the run time compared to the xhp70. I’m not using it much at full output, then again, maybe I do have it adjusted a bit brighter than the xhp70. I typically go full power then drop it down a little. That way I’m getting close to full brightness, but with noticably less heat. I’ll report back on the battery usage in a week or two. First impressions are it can can suck batteries dry quick! Lol
UPDATE: Battery usage is pretty normal. I guess I was just blasting stuff with full power too often. Lol
I also did some distance measurements. At 1 meter I got 172 kcd or 830m. Based on my old throw distances I was expecting more, but I have to remember that this is a “dome on” 70.2. Slicing the dome on my old xhp70 gave a 24% boost. That’s a lot. In theory it would take my 172 kcd up to 213 kcd and throw would go up to 923 meters. Personally I prefer a bigger hotspot with more lumens so I’m not gonna slice it.
well i ended up ordering TA driver everything went well, the only thing that i haven’t done is the indicator LED, i am still waiting on translucent side button from simon. i’ll ask when i hit a snag, but basically the unused 2 pads at the back of the switch board each one powers each LEDs so i just supply + to each unused pad?
It’s supposed to be a 4700 ohm resistor. 47 then a 2 with a line under it. An actual 472 would burn out the led. Since you plan to run 2 leds in parallel you might want a 10k to 30k resistor.
What emitter and batteries are you using? How are you measuring?
18ga silicone wires fits and will give high output.
No I haven’t, since i dont have the translucent switch yet but I will solder the led tomorrow.
I am still using the original Convoy L6 NW emitter and Efest 4200mah batteries (metallic purple). Measured using a single piece of 11cm 10awg cable at the tail and DC clamp meter (Uni-T UT210e)
Okay, that sounds about right. I was getting about 12 amps with my liitokala cells. Those efest may be costing you a little, but no big deal. The NW is always going to be lower lumens than CW, so I’d guess about 5,000 lumen. CW should be about 5,500, so I knocked the output down a little to compensate.
Yeah i am really happy the way it is now. i think going higher would just produces more heat with little increase in lumens. Throw was 78kcd and now 99kcd. not bad i think.
Oh i forgot to tell you that i am using a thin 24gauge LED silicon wire as i need to lengthen the cable so that the driver is easier to work with and i dont have smaller than 16ga, could that also cost me amps?
