In my testing of LED boost drivers, I think I've found another fairly good candidate for 445s.
It's from ShiningBeam, and it looks fairly similar to some drivers I've seen before on chinese gadget websites. It may be a re-sold chinese gadget website driver, I'm not sure. But regardless, this one actually performs fairly well. I just built one of the typical $15 OdicForce "waterproof hosts" using it, and it works great. What I like, is that it's smaller than the NJG-18, so it actually fits in these common DIY hosts (which OdicForce and Rayfoss sell). As always, I used a ceramic SMD cap on the diode leads for protection.
Running it from an AW IMR 16340, it put out 900mA on "HIGH" mode.
It also has MEDIUM and LOW modes. The cool thing I noticed, is that those lower modes are not achieved via PWM like on the AK-007 driver, but rather, they're actually lower current outputs. So, no "blinking" effect to the LOW and MEDIUM, just a nice solid beam, with lower output.
I didn't test the actual output at LOW or MEDIUM, but on HIGH, this guy hit 1,050 mW raw optical output.
Here's the URL for the $5.45 driver from ShiningBeam:

Before anyone rushes out to buy a bunch, lets do some further testing. I ordered two, so I have a second one here. If a reputable member with some experience and ability to really test this driver would like it, I'd be more than happy to mail it off in their direction tomorrow.
