    Involvement Level: Expert (understands the inner workings)

    Pros: Bought as replacement of a foulty cree on a diving flashlight (112889) and works like a charm. probably brighter than the original but with same size. soldering was quite easy

    Cons: maybe it is a standard but + and - sighs dont match with red-blue on the flashlight.. probably it is a flashlight problem..?

    Other: recommended for all diy projects and repalcement of foulty and less quality leds on flashlights

    Pros: Nice Q5 emitter that has good build quality and easy to solder to its place. Fits for many purposes and easy to replace for an existing flashlight. Cheap and timesaving solution. Bought multiple of these for my projects.

    Cons: Nothing construction to say does its job. Well done.

    Other: Cheap and good Q5 led easy to replace. Recommend this bulb.

    Pros: These were recommended as an excellent light source to use with my DIY scanner. This has proven to be true; not to difficult to install and provides plenty of light.

    Cons: N/A

    Other: Already have another set for my next project. I'm thinking of how to illuminate a dresser draw in which my wife is always hunting for something after dark.

    Pros: Great super bright LED! The heatsink section is sufficient for my use; I run at about 350 mA at 5V and it just feels a little warm to touch.

    Cons: The price could be a little cheaper then I would consider this an awesome Cree LED

    Other: Great little Cree LED.

    Involvement Level: Expert (understands the inner workings)

    Pros: Comes mounted on aluminum star Easy to wire Very bright Nice white tint Very easy to solder leads to the + and - pads

    Cons: None really, but not as bright as the newer LEDs (XML, XPG, SST-50, etc). Tint is so white it seems almost blue.

    Other: Definitely a worthwhile purchase for doing custom LED builds or swapping emitters in lights.

    Involvement Level: Expert (understands the inner workings)

    Pros: The aluminum star-mount by itself dissipates enough heat to allow continuous operation at about .75 watts and still maintain the junction temperature below 70 deg. C.

    Cons: Watch your eyeballs!

    Other: Nice white light. Calculations show about as bright as sunshine if focused to about 4in^2. Could be a little cheaper but still reasonable.

    Pros: Is preinstalled on star, so it need less skill to install. While just playing with it for short amounts of time it wont overheat. Cheap! Good color and brightness.

    Cons: For DIY:ers. Easy to destroyed if you donä't know what you are doing. Needs quite a bit of cooling

    Other: Hard to beat price for quite bright light. use them in masses and it still won't burn through the wallet

    Involvement Level: Expert (understands the inner workings)

    Pros: Very good quality products with a perfect installation of LED on a star to heat. Bright white with a nice shade, when the right move at the correct voltage and current. going to be used with SKU 13557 for highlighting the luggage car.

    Cons: DIY item requires soldering skills - Its a bit tricky to solder. Unknown Vf and accurate color temperature. Thick base (good for some things).

    Other: cool

    posted by Polara on 04:30:06 G11T 23/11/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I ordered two Q5 and two driver SKU.26110 to build my front bike light. To drive it I´m using a 16V-8W dynamo, with rectifier bridge and a 2200uF-33V capacitor. I also ordered SKU.18841, SKU.25232 and SKU.13667. i put the led on a aluminum heat sink because it´s operating on maximum current (1 - 1,2A). Using the plan lens, the Q5 with the reflector produces a very strong throw, reaching almost 300m, but a weak flood, which sometimes it´s not enough to a night ride on streets. Using 13667 lens, you get very horizontal-opened light, much more flood that is great for most night rides, without blinding others. To have both strong flood and thrower, I installed two sets on my bike, one with the plan lens and the second with SKU.13667 and a key to switch between them, exactly as a car high/low beam. the dynamo can handle both turned on at the same time, but the light decreases a little and you can feel more charge on your legs, besides the dynamo heats too much.

    Cons: none I can think.

    Other: DX could deal heat sinks.
