Cheap CREE LED lights from Kogan?
Kogan are selling a 1200 lumen CREE led headlamp (no handlebar mount)for $35. Not the latest state of the art however $35 for around 1200 lumens seems like fair value if the quality is ok and the design looks very familiar to several others out there in the marketplace. could be a good cheap commuter light. Anyone have any experience with these units?

Cheap Helmet Light
CREE Q5 LED 300 LM 7W Headlamp available on eBay for $16 delivered.
Was able to modify to fit on helmet by removing the strap and attaching with velcro. Makes a great zoom-able spot light. Uses 3 AAA batteries in a separate battery pack. Runs for more than 2 hours on high using rechargeable NiMH batteries.
Carbon Helmet Light Mount
Prototype helmet mount for Squidled.
Carbon fibre lay-up and a three piece mold. This is the smallest thing I have ever molded in CF, and the mold was a nightmare to design, but the part popped out as easy as anything!
Rob's Mk3 Light (front)
Triple Khatod lens is centre and 10x10mm square Carlco (16 degree) sides.
Note the Khatod lens is 6mm higher than the others so the centre LEDs are set back by that much. Quiet a tricky build.
They are fixed to the 20x20x3mm aluminium holder with Arctic Alumina thermal epoxy.
Rob's Mk3 Light
Mk3 light: 6 x Cree XPE driven at 700mA from a TaskLED MaxFlex. Khatod triple lens + 3 x Carlco 16 degree at the sides.
Fitted to 20x20x3mm aluminium then secured inside 75x25x3mm box section (75mm long so it's square). Covered in LED heat sinks from Jaycar.
Front cover from huge lump of plexiglass I found on the street. Oh, did I mention the box section was also a freebie offcut I found dumped last year and it's driven from an old 4000mAh, 10.8v laptop battery (also free)? Cable is recycled from Mk1.
Gluing Optics
Gluing the optics to LED holder. Note how runny this epoxy is - I don't like it at all, but thankfully it did the job.
The grey thing on top is the perspex lens cover placed there to make sure the centre Khatod lenses stay square.
Emitter Holder
How the emitters will fit on their holder. The whole thing will sink further inside the aluminium box when done but have left it sticking out to show the various depths required.
You can see here that using the square MCPCB with Khatod triple probably wouldn't work.
Carlco + Khatod Height
This shot was to check the height of a 10x10mm Carlco + square XPE (Cree) compared to triple Khatod lens ontop round XPE.
Think the longer legs on the Khatod need filling a little, but the 2x3mm alu (yes - those chunks of aluminium under the emitter/lens combo in the left are 3mm thick) is just about perfect, or will be when they get a little glue between them.
XPE Single + Triples with lenses
These things are tiny!
A sheet of single XPE emitters, with one 16 degree Carlco lens. Then some triples with 18 degree lenses.
The triples fit really nicely, the lenses slotting into the MCPCB. Ideally the singles should have come supplied on square boards so the tiny square lens did the same. It would be nice to get them exchanged but one could make do with rounds with care.
Bike lights - Bflex menu issues
I am having trouble accessing the setup menu on the Taskled Bflex.
The three clicks toggles between the high and low light settings but I cant seem to get the right sequence to enter the menu.
Anyone got any ideas?
Thanks
