    Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:Great color and light output. I mounted two of these onto the metal cover of a small project box from a local electronics store. Managed to fit a 3 AAA battery holder out of a cheapo 9 led light into the box to power them DD. Then velcroed the box in the top of my small... Read more

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day Pros:The LED's themselves are very bright. I have found the following. Soldering to them is weird, using a 18w soldering iron, the solder would take a while to melt, then when it would melt and stick to the pad it would cool for a sec. i imagine this is because of th...

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:This led is very bright, using 2 of them for my bikes tail liight makes it uncomfortably bright for anyone within 20 feet of the back of my bike.

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:Very bright red led. More bright then I expected. I have built a bike tail light with 10 pcs extra bright 5mm leds, but it hides far behind this guy. Cons:Just as any of the power leds, it dissipates too much heat. You need a heat sink. OtherThoughts: Bottomli... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:It's great bright red light. Easy install method, thanks to the PCB star. Cons:Higher drive current, the light color becomes a little bit orange, but it's not a big cons for me. OtherThoughts:I think, this is Cree XR-C LED. I bought this to build a good and br...

    Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:Very bright, it shines at low currents, too. It comes on a convenient star metal core pcb, easily soldered. It came in a tiny anti-static wrap for protection. Cons:The dome was too big to fit into the hole of the lens I chose, so I had to do some file work. OtherThought... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:I bought this to use in a cheap 2xAA headlamp housing to be directly driven. It's quite bright on moderately flat alkalines and doesn't produce much heat. On rechargeables it's even brighter but good heat sinking is needed for extended use. No real problems wi... Read more
