I planned to get the host in hand take measurements and order the diode in a sink with g2 lens from DTR and mount it myself.I would suggest sourcing a heatsink before 100% planning to use this host unless you are going to make your own. Any host will work if you have a heatsink and room to fit a driver.
I read that thread. It is what got me looking at the Ebay host.Hi Aaron,
This is the way i built my XM900 host its the same as yours , this is with a DTR 35mm copper sink and a copper washer to keep it aligned . And this is how i sinked the driver to it with Arctic Alumina Epoxy. No hot glue it has no thermal properties and the driver will heat and die or go on safety. If you didn't know how to build these 44 diodes learn first they aren't cheap if you kill them ..
I would advise against this as well use a proper thermal paste glue it will take longer to set but will be much better then hot glue. The diode will heat the sink hot enough to melt hot glue and then it will fall out I bet.I read that thread. It is what got me looking at the Ebay host.
I don't intend to hot glue the driver to the sink (I am aware how important keeping it cool is, when I typed x-drive I was thinking SXD, I have read most of the NUBM44 MUBM06 and MUBM07 build threads), just use hot glue to fill the gap between sink and host tell a better option was found. Namely a full on custom head assembly.
After thinking about the tools I have on hand I should be able to modify a washer and mount the sink to that then screw the head together to clamp on the washer. I prefer to have the option to remove the diode/sink/driver combo from the host at a later date.I would advise against this as well use a proper thermal paste glue it will take longer to set but will be much better then hot glue. The diode will heat the sink hot enough to melt hot glue and then it will fall out I bet.
I'm not sure of how much gap your expecting but if it's a decent sized gap then you still risk issues using that much paste (alignment, paste failure, etc) and will greatly shorten the duty cycle of the diode even with the driver heatsinked and pasted.
The diode is more important than the driver as the driver is 30$ and the diode is 100$.. keeping it safe at all costs is the most important thing in my opinion.
If your copper module isn't fitting well find something to shim t and glue to hold it all together. Or find a proper heatsink for a different host here on the forum.
Sorry.. just my $0.02
You could use that, but I don't think you will have more than a hand full of seconds run time. The NUBM44 diode is a heat maker, I wouldn't try using a host like that flashlight, not even most of the hosts you find people using, it really needs a large heat sink, not only for the diode but for the driver to sink to also. I used a MrCrouse Mace of Doom host for mine with a huge heatsink on it, relative to many laser pointer hosts, and it has never had a problem. Also, I used thermal heat sink glue, that is, heat sink epoxy to fasten my driver to the inside end of the heat sink and no problems.Just wondering if this 2000 Lumens 5 Modes CREE XM L T6 LED Zoomable Black Flashlight Light Torch | eBay Would make a good host.
Maybe even use the 5 mode feature combined with an X-Drive?
