I assume your using the the xhp70?
Keep in mind that measuring lumens requires a special setup to get any type of consistent measurement. With just a lux meter, you can do simple ceiling bounces to measure increases and decreases in output.
I’ve got a lux meter, but no integrating sphere. It’s easier to just measure the amp draw and consult a chart to see about how many lumens it’s putting out.
Lexel, where did this chart come from?
All the xhp70 test charts I’ve seen shows about 5500 lumen at 12 amps.
Edit: That was with N2 bin. Are the current L6’s coming with N4 bins?
This is a cold Lumens test with T solder point 25°C djozz and others do tests while the LED is likely hotter
djozz has as well N2 bin and has 3750 Lumens at 5A, while this chart has 3900 Lumens at 5A
I would also say that this homemade Lumen readings always can be +/-10% off
yes just the XHP70 at the mo but I do have an XHP70.2 on its way from Kaidomain.com
i was considering following one of Adventuresportsflashlights videos on how to create a lumen Tube. i know it wont be super accurate but will be able to give me an idea on what gains im making while modding.
Lexel do you have a similar chart for the XHP70.2?
EDIT : found it on the website you linked Lexel [LED test, english] Cree XLamp XHP70.2 P2 40E (≈ 4000 K CCT) | Taschenlampen Forum
Lexel, have you ever messed with a Crelant CH10 head mounted light? It has a 22mm driver with the switch on the battery side so there are 2 holes for the E switch wires to go through.
Do you think you could make a narsil driver for this light?
I need to unsolder the emitter to see the component side of the driver, but haven’t done that yet.
I am sure I can make a Narsil driver for it,
I can use a small drill for the wires on spots where the driver does not get damaged
the 22mm driver has 1.1mm blank ground ring to the edge around the driver,
maybe max 1.5mm possible then very close to parts and pads
if this is not enough I could put the new 17mm design on a 22mm board
F*!!! I think I may have just destroyed my Driver. :rage: :rage: :rage:
today I received an SMO reflector for my L6 when I put it in it had a horrible look to the beam. I was trying to focus it and I think it touched the terminals on the Led star. I now have no modes. if I use the rear switch it comes on but I have no mode selection with the side switch.
do i need a new driver?
A dead short with unprotected batteries likely killed the FET, easy to repair if you send me the driver, I had one driver before that got killed that way
Removing the FET and the light is at least useable with AMCs in the low and middle modes
If the FET is conductive when you use a DMM it needs to be replaced, not sure if you can do a reflow of it on your own if I send you one
I still need 1 driver 30mm NarsilM 1S PO=NO SD=3V 50°C, lighted sideswitch (9k if possible) , with tracking shipment , thanks.
Ok I put you in my list this week I should receive 6 more 30mm boards the 3 here are 2S build
Are you shipping with NarsilM 1.2 yet? Thinking of getting a driver for my L6 soon.
you can add a 1S 17mm NarsilM 60°C, SD=2.8V, PO=(NO) indicator led but no resistor, no spring, driver to my order 
Ok I got here one Narsil 17mm build but soldered already ba accident spring and cables to it, but got an error when I tried flasing Bistro OTSM :person_facepalming:
Any lead time on the 21mm drivers?
Oshpark shipped them friday 10 days ago, should be here any day
The other manufactory with 230 single boards on 20 10x10cm PCBs are still not even produced
I’m not sure if you got my pm, but is there a 17mm driver with Narsil left for sale?
Hi,
I got ordered a very big amount of boards from Seeed, when they arrive I can make more 17mm drivers, last week the last 17mm sized got already taken
I hope they will deliver soon
Hi Lexel how much is it for MF01?
