  • protection for SCU 81926

    posted by andreyua00

    A good thing, but useful only if the SCU 81 926 used on the street. It can serve as protection for the LEDs. In The room - it is useless, no influence light distribution does not have.
    But, but with this lens, the lamp has a very good view.
    If you intend to use the specified lamp at the inside - you can do without this lens. Add this amount to buy a good driver, it will be much more useful. Or on a large radiator - not too bad.
  • acrylic collimator optic.

    posted by lasermanathome

    The nice thing of these kind of optics is the high percentage of transducing light into a beam wich has a divergence comparable of a wideangle laser.Expecially with R2 leds, it is difficult to beat the divergence, even recoil led flashlight included.Can easily made fit in W501 as an alternative for its reflector.
    Other leds , like the t6(60) do not reach the same collimattion, but the led itshelve is much less visuable what can be a great advantage.Also is the captured light MUCH greater than with a reflector.That means that more light can be guided to the place you want it.
    Low costs, nice optics for people who like to experiment with light.These optics are VERY suitable for IR powerleds.The one Watt version gives a more satisfiing result as the 3Watt led wich has 3 one Watt cristals but not in center of that type powerled so even collimation with this optic gives not a nice spot.
  • Hard plastic 3-in-1 LED lens

    posted by Korkonen

    3-in-1 LED lens made of hard plastic material. The three lenses (and hence LEDs) are grouped quite tight together, enabling flashlight/bike light construction with three power LEDs within 50mm diameter. Seems to produce a nice beam with little light lost through the sides. Flat front plastic eliminates the need for a separate cover glass.
    The opening in the lens is a little bigger than your typical power LED, and so allows small adjustment to get perfectly symmetric beam. On the other hand provides some tolerance on the relative positioning of the LEDs when mounting them on a (metal) heatsink
    A good 3-in-1 LED lens for building a flash light, head light or a bike light etc.
  • Best 3D glasses I've tried.

    posted by Paddan1000

    Comfortable.Durable.Little or no ghosting, depending on the source material.Nvidia branded.
    I bought three different pairs of red-cyan 3D glasses and these were the best of the bunch. Also available in green-magenta.It says "Nvidia 3D Vision Discover" on the frame. Whether the branding is genuine or not, it makes them feel like a true computer peripheral and I use them for 3D gaming with my Nvidia graphics card.
    If you have a hard time choosing between all the different models of 3D glasses sold on Dealextreme, choose these! I would definitely order again if I needed another pair.
  • good product for soft light

    posted by karelgott

    I needed soft light. It's a good product, cheap and its degree is suitable for video lights. .
    I use it on my DIY video lamp. I have a Luxeon Rebel Star led.
    I recomend it for DIY projects. ..........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
