The 12w Arctic Blue that came with my Consular died last week
 I undid the grub screw then pulled out the heatsink/led assembly and there's no wire break, soundboard still works fine, so pretty sure the led module is blown. I'm looking to replace the led and have access to tri-cree xp2's here in the UK. I'd order a replacement from Saberforge, but I really cba with the import shenanigans I've had to go through in the past to get even minor stuff from the US. So, questions - there's no resistor on the Saberforge 12w unit, does the Viridian soundboard limit the voltage itself, or does it just dump the full 3.7 v from the battery and these 12w led's use the lot? I don't have a meter (on the shopping list) to check the voltage myself, so a heads-up would be appreciated so I can calculate the resistor value for the replacement tri-cree module. Much appreciated folks

No, the soundboard doesn't limit the voltage. The Cree XP-D (the type of LED SF uses) blue and green dies that make up a SF arctic blue LED have forward voltages close enough to the battery voltage so they don't need a resistor and can be overdriven a bit.
As for the forward voltages of Cree XP-E2s, that info should be available from wherever you are purchasing them from, such as LEDsupply, or a quick google for "Cree XP-E2 spec sheet". On a related note, how long have you had your saber? If the LED did blow out this would be covered under the saber's one year warranty. |

Thanks for the reply.
I'll need to resistor the tri-cree's, as their fv is 3.1, not a problem. I was being cautious as I know the Sabercore boards are a custom job and may well have their own voltage regulator and lacking a meter, I couldn't check whether the 12w xp-d module was indeed getting the full 3.7v + current from the 18650 battery. The Consular is about 18 months old at this point. The cost of sending it back to the US even if it was in warranty is prohibitive and you run the risk of getting stung for duty & handling fees on it's way back. Not to mention the time it would take and as it's my kids saber and he played with it daily, that would be an issue. Think I'll bung quick connects on the cables while I'm at it, make it simpler in future should I have issues again down the road. I was also considering trading up to a NB3.0 board, but man those hilts are small on the inside. The internal diameter is quite a bit narrower than usual. I'm balking at even trying the job Thanks again. |

XP-E2 royal blue has a fV of 3.1 @ 300mA but 3.4 @ 1000mA (which is the value you need for this application). You can still use a resistor if you want, and get some better battery life at the cost of a bit of brightness. Or if you do swap for a NBv3, you can adjust the drive setting slightly instead of using a resistor (since the resistor value will be so small). The nice thing about having a current of 1000mA (or 1A), it makes the resistor calculation super simple.

With how small the Consular is, the quick connects might be a really tight fit. If they're just for maintenance convenience, that'd be alright; but if you plan on swapping the LED out a lot it might be more of a hassle. As for swapping for a NBv3, I know it can be done in a apprentice hilt, but your Cram-Fu game would have to be on point! Good luck on whatever path you choose, and share the results when you are done! Thanks again.[/quote] |

I was thinking of going with standard blue-blue-blue. Looking at all in context, I think I will be hard pushed to get a NBv3 in there, otherwise I'd make plans to have foc, so maybe blue-blue-white in that case. Not likely to happen though and I don't want to start snipping the recharge port and switch wires to pull the battery & board out and see exactly what sort of space I have to work with. How comparable size-wise is the NBv3 to the Sabercore? Anyway, I have one of the excellent Photon Blades obtained from JQ sabers here in the UK, so I have that as a color change option too. I think the regular tri-cree XP2 blue is the "best" wavelength match to get the most out of the photon blades. There seems to be plenty of space between where the led module sits and the first obstacle in the hilt (the switch) so hopefully quick connects aren't a problem for future ease of use. I will indeed post a pic or video once I'm done (y) |

The NB is quite a bit smaller. It's 1.12" long by 0.73" wide.

I don't want to de-rail the discussion, but is this why many custom installers seem to gravitate toward the NB boards? I want to try one and never have. |

They're small, super straightforward to wire (no need to bridge anything like the Tru Drive on NEC boards), relatively inexpensive, and have a decent selection of features.

Thanks for that. Given that an NB is physically smaller than the Sabercore board, I guess there's room in there after all for an upgrade and a b/b/w tri-cree for foc to complete the picture.
The beauty is, I can use pretty much all the existing wiring without having to change much also. Result
