BLF Interest list for Very High Current Beryllium Copper springs Pt1(ENDED)

The nice thing about silver is that silver oxide is also an electrical conductor.

But hey, a few dimes and nickles more for gold plating won’t worry me at all if you choose gold again.

BlueSwordM · 2018-11-22T01:39:51.000Z

Yeah, but instead of costing around 365$US(without shipping and taxes), it’ll cost 750$US+ to order a bunch of gold springs, which would be very costly for me. Going with gold would obviously be the best, although the difference would not be as large as going from nickel-silver, than silver-gold, which is the reason I chose it.

And silver is better in most cases for spring usage in our flashlights, due to the fact that they are in an enclosed space.

I also calculated, with some input with the manufacturer, that the electroplated silver layer, in a single bath, could easily be 20um thick, and the gold plating would be around 5-6um thick, and cost much more.

So finally, I chose silver as a plating material. Best of both worlds, being way better than nickel while still being close to gold as the best spring contact material for our purposes.

Good choice BSM!! Glad you passed on the Gold…. price is to much.

timbo114 · 2018-11-22T06:43:05.000Z

I’ll be in on the new batch with electroplated silver.

Leave a message for which order you want. One per person!

The only people left to fulfill the orders are teacher and Lexel, which are exceptions I’m currently taking care of right now.

Tom_E · 2018-11-29T03:41:25.000Z

Got my order of 25/25 springs. Thanks!! I'm talking with Tracy at Sofirn, recommending the large springs for use in the Q8 - dunno if it can happen but she may try contacting you.

The Sofirn Q8 has some minor improvements, but biggest difference is the XPL HI's - I measured just over 100 kcd in stock form with 30Q BT's. Think these springs would work well in it, we'll see. Just might upgrade it with the springs with a detailed before/after tests.

BlueSwordM · 2018-11-29T03:49:20.000Z

Honestly, you’ll be very impressed with them.

I actually did a tailcap mod a while back, and here are the numbers.

My lumen numbers on the Q8 with the normal lens and steel screws were 5230 lumens.

My numbers on the Q8 with the Kaidomain AR lens were 5649 lumens at 30 seconds, with brass screws. I didn’t actually gain as much as expected with the brass screws, since the steel screws were tightened to the max and have a very wide contact area. The AR lens made the highest increase.

My numbers on the Q8 XP-L HD with the replaced springs and AR lens are now at 6764 lumens! at 30 seconds, with brass screws.

If you don’t have the same result as me(lower), then it’s probably due to the lack of an AR lens. You should still see very nice boost in brightness.

If you had the XP-L HD version, you’d probably be getting around 6400-6500 lumens at 30 seconds.

Tom_E · 2018-11-29T04:23:30.000Z

Yeah, I modded a bunch with bypass wires, but it's a PITA, so looks like these springs get bout the same results, but 6700 is wayy up there with my best Q8 mods, I think what I recall... I also swap the FET's to better ones: SIRA20DP or the Infineon one. Also used UCL and UCL/p lens.

BlueSwordM · 2018-11-29T04:28:53.000Z

Yeah. I also probably got the highest brightness variant of the XP-L V6 3D, so your mileage may vary a bit

But honestly, the combination is very potent.

DB Custom is getting 21A/spring array in his 4P Q8 Super Saiyan HMR or something.

Lumencraft-Matt · 2018-11-29T18:38:32.000Z

Just in case anyone is still wondering these are A+ grade springs. Easy to solder to as well.

BlueSwordM · 2018-11-30T01:19:37.000Z

So, guys and gals, the 1st BeCu VHC spring group buy is finished.

I will be shipping the last of the orders tomorrow, and my big spring box is now empty, as expected

Thanks blue. Hats off to you.

The envelope arrived.

Thanks!!!

Lexel · 2018-12-05T21:12:13.000Z

funny I am on list and never got a PM to pay my order

clientequator · 2018-12-05T21:13:03.000Z

Hi, are there still springs for sales?

BlueSwordM · 2018-12-05T22:08:20.000Z

@Lexel, I made an exception for you. I knew you had a lot of work with drivers, renovation, so I waited for you to either ask or notice you still didn’t get a PM.

Your springs are ready to ship, and will be shipped tomorrow.
