For me they worked but felt just a little too tight. I cut the down with some pliers and they work perfectly

g_damian · February 24, 2018, 10:36pm

I have 2x bronze springs in S2+. With 18650 tube they were very tight, but still acceptable with unprotected cell. With 18350 tube they were too tight, I have cut down one of them by half.

i42dk:

Mini review of the LD-A4 3Amp + ILC-0 I wanted a nightstand light for a while now, with a illuminated tailcap. But havent got the skill/patience to add a bleed resistor to a driver. So when i noticed the LD-A4 that had it built in, i ordered it immediately. And the ILC-0 (Default LEDs Current). Also ordered a red Convoy S2+ because i like the look, and the metal switch. The light is going to be a nightstand light, so it’s never going to see hard use, so the IPx rating was never an issue. I also got the 60* TIR lens from the convoy store to get a wide beam, as it’s being used indoors, on very short distances. Often in complete darkness, so no hotspots The internals came way before the host, so i mounted them in a BLF A6 host temporarily. To tryout the driver, settings n such. I did run into the black gasket on the metal switch -issue. So until a clear gasket arrives in the mail, the light has a clear rubber button installed. Also had to grind down the inner side of the driver retaining ring, as it was touching the LED +/- solder. The ILC-0 (Default LEDs Current): is perfect for a nightstand light, it’s very very subtle, just the right amount of light. The LD-A4: Very impressed. Genius menu/submenu setup. Very intuitive. The emitter is a Nichia 219C 4000K. So I like that i can choose between “Constant current and Direct drive on high mode” in the menu. And the other options, very much can be changed in the menus. The ONLY complaint i have against this driver, is the moonlight mode. There are three current settings for moonlight; 2.5mA, 5.0mA and 7.5mA. I wish a lower option was possible, as 2.5mA (in my eyes) is still too bright. Other than that, this is by far my favorite 17mm driver :heart_eyes:

Thank you for review! Lower current moonlight modes are possible, moonlight is dependent on two small (0402) resistors, so without hot-air and steady hand it's hard to do for most people, but if you want custom low current moonlight, please leave a note during future orders,and I will change resistors.

Digikey and Mouser have 90CRI 3V version, so I don't have plans for that LED, unless interest is big enough.I'm still considering 5000K 70CRI variant which should be available in T flux bin, but only if there is also enough interest.

i42dk · February 25, 2018, 10:59am

Well well well, you have yourself another order coming soon

So what mA should the target be? Perhaps someone else can chime in.
My benchmark is the ReyLight Pineapple’s moonlight mode, or the BLF Q8 Narsil moonlight level 2/7

Thanks for the feedback!

What about 32mm 3x 3535 Mosled board with Fet and temp conexion? I think it will be popular for x6,c8 and others builds. I will I would buy a couple of pieces, for sure.

led4power · February 25, 2018, 2:35pm

Just one note: you can choose two moonlight currents, third current is I1 + I2 (default I1=2.5mA, I2=5mA, I3= 2.5+5=7.5mA)

For example you can have I1=1mA, I2=2mA, I3=3mA etc.

Noted :nerd_face: :+1:

led4power · February 25, 2018, 2:46pm

I will do that in next mosX batch, plan is to make 31.2-31.5mm (to fit EE X6 without sanding) MCPCBs for triple CUTE-3 and quad CUTE-4 35mm optics, with central hole of course, and with 3535 and 4040 footprints.

Also I want to make 30mm mosx triple 4040 for Sofirn C8F, triple reflector on that light is great.

alberto7 · February 25, 2018, 3:29pm

Good news Neven! Continue the great work

1C3 · February 25, 2018, 4:34pm

Triple 4040 for X6 triple would be great, in fact I’m going to put my next X6 triple project on hold now that I know it’s coming. I’m wondering if luxeon MZ is compatible with CUTE-3-SS? For sure it must work nicely with CUTE-3-W and CUTE-3-M.

contactcr · February 25, 2018, 7:10pm

I would also be in for a cute3 4040 board

alberto7 · February 25, 2018, 7:16pm

Me too, the c8 triple its on hold, and now it will be Quad C8. The existence of CUTE-4 had gone unnoticed for me.

1C3 · February 25, 2018, 7:52pm

Right, I didn’t even think about the CUTE-4.
Now I’m thinking about the crazy amount of current a quad fet-driven Luxeon MZ will pull with the super low vf, we might be getting to the point were the small 1288s will finally start melting :smiling_imp: .

The_Driver1 · February 25, 2018, 8:04pm

I have been thinking something similar. I have a Cryos m2 cooling bezel (p60 head with a lot of deep fins) which has never really stretched its legs. 30A sounds nice with a Samsung 30T :D.

PH_Oton · February 25, 2018, 8:35pm

I am constantly searching for a source of 30Ts on web but so far I haven’t found anything except one company located in India that is specialized for electric vehicles.
According to their website they stated having 30T in minimum oreder quantity of 100 cells. I haven’t contacted them and don’t know if some of us forum guys did. I was thinking on idea of group buy but I doubt this cell will be accepted buy people at current time due to absence of lights/ hosts that would accept them or ones that could be bored to accept them not counting 26650 lights. Maybe those vapers would jump in but I am not in that scene.

Edit: Seems like Voltaplex have them in stock with minimum quantity of 50. Hope? :heart_eyes:

KawiBoy1428 · February 25, 2018, 8:36pm

M2 Cryos head with what battery tube/host? Most can’t be bored to 21+mm…… the threads on my 5Mega host at the tail cap measure 21.76mm. http://www.cryosillumination.com/

The_Driver1 · February 25, 2018, 11:21pm

I don’t know yet, maybe a custom battery tube would need to be made. That would actually be a better solution anyhow because I could skip the p60 pill (bad for heatsinking) and integrate the heatsink into the battery tube.

Such a tripple might actually pull too much current though pushing the LEDs past their maximum brightness.

BTW: Samsung 35T are already listed here.

vinte77 · February 26, 2018, 2:07am

Can somebody post a link for the MZ 90CRI 3v 5700K from digikey? I can’t seem to find the correct one.

PH_Oton · February 26, 2018, 6:59am
