Hey great build man ! Love. That. Cyan!
So I decided to cannibalize my "old" 462 nm 1.7W and recovery the awesome host to use with this stunning diode.
I never imagine to have a so beautiful color with a so powerful output in a so fantastic host :bowdown:
Here is the full story:
Assembling the switch:
Soldering a neodimium gold plated disc on the top on the spring to maximize the battery contact:
Inserting a piece of acetate foil into the host barrel to avoid battery shakes and rattles:
All the parts ready to be soldered and assembled:
Placing the driver into the heatsink and soldering the washers:
Assembling the heatsink:
Connecting, soldering and thermal gluing the driver to the heatsink:
The host fully assembled:
The host clamped on Manfrotto tripod:
The diode performance on three elements glass lenses : drool: )
The awesome beamshot:
the output power with three elements glass lenses is impressive, far beyond my best expectations!
I used LG INR 18650 3000 mAh 20A high draining cells, that is a must for such kinds of current hungry diodes
(the driver is set at 4.5A).
The divergence in the slow axis is a bit more of the NDB7675 1.4W 462nm diode.
This diode generate really a lot of heat! Also the Cypreus II XL has difficult to manage such power: at 26 °C room temperature the heatsink become warm (near hot) after 90 seconds, so I suppose that 60 seconds runtime should be a good time for such host in summer time.
During winter season surely the time can be almost doubled.
As the graph shows, there is an noticeable loss of power as the heatsink warm up.
Despite the not-ideal working conditions (high temperature, pushed near the knee and without protective can), this diode seems to be very strong and show a really beautiful light blue beam.
This is surely the diode of the year.
Thanks one more time to DTR and Sinner!
