    Pros: Tested it direct driving with 3 x AAA's battery while waiting for my driver to come , im amazed with the brightness even though i measure it only 200ma on tail but its bright, now i just need to wait for my driver to come and proper battery setup will drive this thing brightly.

    Cons: Nothing much, i din expect this led emitter to be in such a good quality, as im just using it to replace my cheap china made flashlight.

    Other: Definitely good buy , very cheap and great quality .but as usual takes time to arrive at your place unless you pay for the shipping fees

    Pros: Upon visual inspection when recieved, this is a high quality unit. I upgraded my TikkaXP by directly exchanging with the original unit. The P4 is extremely reliable and has just the right color for my outdoor use. I have been using the light regularly in both of my headlamps for hiking. Seems to me using this led has increased the usefulness of my lights. Great and simple upgrade.

    Cons: Don't assemble in a dirty area. The sticky dome can be cleaned if it gets dirty with some alcohol and a soft cloth. Honestly, you will not have any trouble. Especially once installed in a sealed unit.

    Other: Very good LED even when compared to CREE. Not as white. To my eyes it has better luminous volume.

    Pros: +Awesome pricing for an LED that can take a pounding! +Very bright, and will last for a LONG time if you drive them with a regulated power supply such as sold here on DX. +Every unit I have received has worked flawlessly to date +junctions are solid, wafer size is small compared to other brands.

    Cons: -Some of the LEDs are mounted a little crooked on the star PCB. While this does not affect performance of the unit, it does cause some issue with alignment in optics. - Domes can sometimes tear off of the housing. Exposing the die and causing failure. - Some units get too hot, burning the junction, even at normal operating specification. - Packaging varies. One shipment I purchased was well packaged in a black plastic anti static strip from the manufacturer. Another shipment of LEDs were packaged in anti static bubble wrap only. One Dome was torn off.

    Other: You can't beat the price of these, and they work well in many applications. Pick up a few to save! Best price I have seen for these anywhere!

  • Star mounted SSC P4 U-bin LED

    posted by Black_Rose on 10:05:12 G2T 28/02/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - very bright
    - more than half the cost of other sellers
    - almost a direct drop-in replacement for star mounted Luxeon I & III LEDs.

    Cons: - Only an issue if you are swapping out Luxeon LEDs. The overall height of the LED + star is slightly smaller than an equivalent Luxeon LED + star. May result in slight beam issue
    - When I ordered these they were listed as "In Stock: ships in 1 to 3 days". They went on back order twice before I actually received them.

    Other: - excellent LED on it's own or as a replacement for Luxeon LEDs.

    posted by kuksul08 on 21:50:09 G1T 05/01/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Great price, Easy to install (same form factor and optical properties as comparable luxeon emitters so it's an easy upgrade), very bright, efficient (has run for hours on end in a 3AA direct drive headlamp with minimal dimming)

    Cons: Gummy dome is kind of weird and collects dust just by looking at it, slight greenish and bluish tint

    Other: Excellent LED for the price. I have yet to try cree emitters but this is a tough one to beat!

  • Excellent not only for upgrading older lights

    posted by Thyra on 08:17:28 G12T 31/12/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Bright and good color temperature. Bottom of star PCB is isolated from chip.
    Excellent for upgrading older lights, because optically compatible with Luxeon III.
    I have bought ten or more over the last months and was able to upgrade many of my own and my friends lights. I'm going to continue getting these as long as there are upgradeable lights around.

    Cons: Received one of at least ten that I bought, where the bond wires didn't contact the die so the device was lost (obviously by the time I found this out, I had removed the dome).

    Other: While I personally buy these LEDs for upgrading older lights, they are generally good LEDs in respect of price, color tint and brightness. Can't go wrong with these.

  • bright and 120 degree viewing angle

    posted by fishmarket on 21:07:52 G11T 01/11/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: great price, bright, appears good quality and works well with SKU 3256 driver. Bit of warm one lit up, woa, it's only 29 C though I am not sure what's current from the driver. I used 6 V 400 mA power supply as input to the driver circuit. So with 80% efficiency, roughly 2 W driving power. So the LED is under driven. But it's still bright enough as table light.

    Cons: order take too long, more than two months. However if you can wait, it's worth it.

    Other: This LED is 120 degree view angle one. So good for table light. If you want use it for flash, the lights is kind of flooded. My flash light doesn't have adjustable focus, so i don't whether those flash light with adjustable focus would help or not.

  • a fine upgrade from a Luxeon III

    posted by isti.242 on 03:40:53 G9T 08/09/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It's an affordable, quite efficient LED with good brightness level. Mine came bubblewrapped with correct polarity indications on it. It has a nice white color.

    Cons: Not really.

    Other: It's a good upgrade solution for an old Luxeon based lamp. Get it! :)

    Involvement Level: Expert (understands the inner workings)

    Pros: Ideal para upgradear linteras con leds similares pero menos potentes. Yo por ejemplo lo he usado para dar más luz con un frontal de leds modelo Myo XP de la marca Petzl.

    Cons: Hay que tener cuidado al soldar el led, pero en verdad ninguna pega achacable al producto en si.

    Other: No dudes en comprarlo si tienes una linterna de leds que quietes potenciar.

    Pros: Plenty of light. I have found that the Vf is sorpresively lower than i espected. For the work i have used the two ones i have purchased (a bike, dynamo, powered frontlight), they are perfect.

    Cons: The dome is rubber like. Really not a DX con, the units provided by seoul are this like.

    Other: A note for DX: I think there is some chances of doing business with some bike dynamo driven light. There are almost no models in the market and at no atractive prices. I think is very convenient if they are "standlight" capable. That means it is capable of run some minutes in a stop, thanks to a set of ultracapacitors.
