My Convoy L6, lighted switch, TA FET driver plus mods

You can learn a lot more here than from me.

Narsil M thread

For this case, The inducator led works still?

and

LVP is set by R1/R2?

I have no idea. You need to ask Tom or Lexel, etc…

if 2S LVP is set by R1/R2 the MCU pin is blocked by this voltage divider, so no indicator LED feature in firmware NarsilM active

still you can light your sideswitch over the battery voltage, but without overdischarge protection as you directly drain the battery

This is true on any light (unless the indicator light was monitored by the LVP circuit), but I don’t think this is really an issue. I mainly use the sideswitch light to tell me if the rear switch is on or off. If I’m not using the light, I turn off the rear switch so there is zero drain.

could you upload your pictures to another hosting source not blocking 3. party use?

Once I find the time, I’ll look for a new hosting site.

I’ve got a couple thousand pics, so it’s going to take a while.

Recently Photobuckets website has been super slow due to all the people pulling their pictures off. I was able to get a few hundred, but gave up.

Hey Jason

can you post your side switch led with resistor?

tempting to mod mine too

Photos are not linked?

I’m trying Imgur and it seems okay, but not great.

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

Just kidding.

Yea Imgur has become rediculous to upload pictures every since the photo bucket hosting price explosion.

In what way do you mean?

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.

All I know is that it seems to be much slower uploading than before the changes with photo bucket. It seems almost that the servers are overloaded

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.

@JasonWW: what is the sense resistor dimension being used by the FX30 driver?

It’s right here. 3.2mm by 1.6mm 1/4 watt. I’m not sure what the 1206 refers to. Either number works.

It’s 3216 or 1206. It’s the same dimension, one is in metric, other in imperial.
3.2 mm * 1.6 mm or 0.126 in * 0.063 in

thanks, i’ll order some resistor and try to boost the current on my L6 a little.
