I made and checked a new reference light for output measurements

Unlike with flashlights () it felt a bit uncomfortable opening up a brand new power supply, but here are 4 pictures (I give links because they are quite big and I don't want to ruin people's page loading time):

I am not an electronics guy, so although I have a general idea of what is going on in there, I haven't got a clue if what I see is good or not, or if these pictures even show anything relevant to compare it to other power supplies.

I was merely curious what you had done to the light to get that kind of output. I have a lightbox given to me by friends and calibrated by them with a rather extensive base of lights. It is fairly difficult to get true Out the Front readings such as that.

That being said, I built a Convoy S6 today using the new BLF 17mm DD pcb and FET and with really good cells I am getting 6.95A at the tail and 1377 lumens at start, with 1211 lumens at 30 seconds Out the Front. This is, I believe, an XM-L2 T6 3C or 3D emitter on a SinkPAD.

I also tweaked a TangsFire TS2010 to get 5.46A from a Sony C4 18650 for 1656 lumens on start up and 1556 at 30 seconds. This is an XM-L2 U2 1A emitter, still domed and mounted on a Noctigon.

The light in my avatar is a Solarforce M8, with 8 ounces of copper for it’s heart (made by fellow member Bucket), with the MT-G2 on a Noctigon and reflowed directly to the copper pill. It makes over 4200 lumens at start up, and 3600+ at 30 seconds, creating quite a lot of heat in the process! It too is utilizing an FET modified driver, pulling 10.81A at the tail.

Fun stuff! :slight_smile:

Good luck figuring out how to make these issues universal, as the variables are quite troublesome.

djozz, that looks like a very robust power supply (not that I know much about these things but still) Enjoy it man! :slight_smile:
