I bought my Nubm44 from DTR mounted in a 20mm module including the driver pre mounted and a G2 Lens.
Spent some time building this host. My aim was for non stop operation without any heat problems. I ordered an 80mm x 25mm x 150mm Aluminium Flat bar from a local supplier on Ebay. Some spare time at work with the Mill I shaped it and drilled a 12mm pilot first. Then I drilled it out to 20mm about half way thru. The Idea is I can use this block to mount a 20mm or a 12mm module. Drilled and tapped holes for two 3mm grub screws to lock the module in.
Next was the heatsink blocks. Ordered 4 35mm x 35mm x 15mm heatsinks from Ebay. Used thermal adhesive pads to stick them down. Then installed an 80mm axial fan to give air flow. Way over board I know. But hey, Lets keep it cool.
I needed to order a Hyperion LPM capable of measuring this massive Diode. I ordered the 20 Watt version. After some problems with the display in the Hyperion I had to replace it with one I bought locally..
I have no idea what current DTR has set this driver to. It seems to have a very high output. Assuming a brand new Hyperion is calibrated accurately.
Wearing safety glasses without my reading glasses on it was hard to read the blue display on the LPM. From what I could tell it was stable around 8300 most of the time. I let it run for about 60 seconds for the test. It's only a 6mm x 6mm sensor. I focused the beam to fit all of it on the sensor.
Have a look at my pics. The output seems to high. But this is what it measures.

. 8.4 watt does seem kinda high, you might want to get a second reading somewhere to confirm, but if so, one powerful build. :gj:
This one time we can live without a nighttime beam shot..
