This will be my review of the Flaminpyro SS-032. This started out as a single flexdrive at 1.5A however in the push for more I decided to go for a dual flexdrive setup. Both flexdrives are set for 900mA a piece. At this level I found zero heating problems and no need for heatsinks on the drivers. It would have been extremely difficult to heatsink them both in this host anyway. A single flexdrive would burn your finger quickly at 1.5A and at 900mA I barely noticed warmth. Testing was done with a 405G1 lense but normally I use an Aixiz glass.

Here I am setting the drivers up at 900mA each, and testing together at 1.8A

The end result 2.147W

I have now found the need for premium 18650's. The Trustfire's being good for the money for most things are taking a beating at this current draw.

You may have overflowed an integer depending on how many nW it outputs... :p

Looks great! I still need a handheld 445nm.

Great build ! Dual Flexdrive setup really rocks !

You must be holding the record for most powerful handheld laser.
:lasergun:
 
I like this host design. It reminds me of SU25's rocket pods.

Hmmm I wonder who dose really hold the bragging rights to the most powerful hand held laser...


Either way, Sick build!! what's the duty cycle on this beast?

Very short I'm sure. I use the same host (SS18650 build by jayrob) and running it at only 900mA it still heats up relatively quickly (ie 30-60seconds or so). So at double that power... it would heat up pretty darn fast. But in all fairness I rarely have need to actually run my laser very long at a time, and given it is pushing out over double the power would mean it would be burning stuff even faster thus reducing your need to power it for long. I expect at those powers realistically he's probably a 15-30second duty cycle, I'm sure you could push it more than that but you probably wouldn't want to push it too far.
 
Very nice.

Can you make a video showing the power drop in that host in a few minute run? I would be interested to see.

Anyway great job. It is good to see others pushing their way up.:beer:

If he pushed it anymore it would just shut off. We had a member push it well over 2W w/o the 406g1 lens, and it shut down. Then it came back to life after he turned it down. But then it degraded very fast, and zombied IIRC.

@DTR Good point.

No no, that comment was in reference to pushing the duty cycle, not increasing the power :). I generally play it pretty safe on overheating so there is most certainly room above the numbers I stated, but I would expect a normal duty cycle to follow somewhere around those numbers in this host.
 
The FP heatsink does have more mass than Jayrob's design. Obviously this isn't a huge host with a huge heatsink however at 1 minute runtime it is quite warm. At 2 minutes I would consider it hot. Ive really had no need to run it more than 1 minute at a time. I currently have around 30 minutes runtime so far with zero degradation.
 
I just had the meter to above 2.4W by adding my red at the same time.
 
Great Job :) a very powerfull build.

I think DTR's remark is right : They won't be balanced, so adding HS to the driver is a good idea.
