    Involvement Level: Expert (understands the inner workings)

    Pros: Good and cheap LED with a brandname. Very good deal. Regret I haven't bought more, but I will. Very bright light already with 300mA. Easy to solder, easy to mount

    Cons: None actually, or it should be that it is a bit unclear what the max current is.

    Other: Buy, buy more

  • excelent blue led

    Involvement Level: Expert (understands the inner workings)

    Pros: easy to use easy set up original Cree led very very bright like black light

    Cons: no specs at all are not all the same blue wavelength (i bought 25,and there are almost 3 different blues) *** don't look at the led during it is on*** or you will be blind like 5 mins.

    Other: DX support, expressed that is a XPE, for me is a XRE model(even dough, both must run up to 1000ma MAX) the differences between 350 and 650 by human eye are minimal (almost negligible)

  • Small light source

    posted by Vaskeklut on 13:21:50 G2T 26/02/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I bought this light to make myself a glowing glass bottle (Nuka Cola Quantum). I find that the light is seriously blinding, even with just two regular 1,5V batteries! Guess you could illuminate a small room with two "game boy-batteries"!

    Cons: It works by connecting the small areas on each side with +/- on the battery. This means that you will have a hard time setting this thing up unless you have a two cables and solder or a socket. Took me some time to get that in place.

    Other: Use this or SKU: 9077 if you need blue light. Ordering ten of those now.

    Involvement Level: Expert (understands the inner workings)

    Pros: Original Cree LED

    Cons: Availability? It took weeks until my LEDs were ready for shipping...

    Other: Very nice binning. See the user photo section for more details. All of my (atm) 8 LEDs have very very similar light output at any current, so it should be even possible to use them in parallel circuits (but not recommended). Minimum voltage until they had a very dim, barely noticeable light output: 17.8 volts for 8 of them, thats about 2.2V per unit. Voltage at 300mA current was about 27.0 volts = 3.4V per unit. Keep that in mind when designing a driver circuit for them. Maximum current is still to be determined. At 300mA they do not even get warm, but have a HUGE output.

  • Good and Original LED from CREE

    posted by ben1680 on 09:30:22 G3T 08/03/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Good original LED from CREE

    Cons: None

    Other: This is original Cree LED. There is no info regarding brightness bin code or color bin code. It should be included for information purposes. As far as I know, it should be Cree XR series led. Cree brighter LED, XRE series, only available in White color in various bin code from warmer white neutral white, and cool white. The price are not bad though and the color rendition are pretty close to stated color. In this case, this blue LED is blue in color without leaning off toward cyan or UV, at least to my own eyes.
