  • Good product but narrow spotlight

    posted by stopsi

    - Very bright at spotlight
    - nice finish & look
    - looks professional
    - constant light circle, very regular shaped light
    I have 7W "energysaver" spotlight bulb too, and this is much brighter (3W!) at spotlight but much narrower beam... Old energy saver beam is something like 180° but this is maybe 10°
    Very good when you need bright and narrow-beamed spotlight
  • Convex Lens MR16

    Construido con un buen material. La cobertura principal de la lámpara es de aluminio lo cual ayuda en la disipación del calor. En caso de falla es muy simple acceder hasta el diodo led de la lámpara. La luz que emite es de color azulado frio.Built with good material. The main envelope of the lamp is aluminum whereby the heat dissipation is good. In case of failure is very simple access to the LED lamp. The light emitted is bluish cold.
    La lámpara genera muy poca temperatura y da para tocarla mientras se encuentra encendida.The lamp generates very little heat and gives to touch while it is on.
    Como conclusión, es una lámpara para ser usada en lugares donde no se requiera mucha intensidad luminosa. In conclusion, it is a lamp to be used in places that do not require a lot of light intensity.
  • Great flood emitters at great price

    posted by yrnkrn

    These are great flood emitters at great price. The Cree XT-E are among the newest and most efficient emitters available.
    I build a rechargable emergency light with two of these and no optics. At about 10W it provides great amount of lights, as much as a 26W CFL. Maybe more. I plan to replace some CFL lights in my house with custom build XT-E and XM-L Cree lights. the cree efficiency on paper is about twice as the CFL. Practically it is less but still much better.
    Great buy.
  • Cheapest XML on DX

    posted by desolder

    This is the cheapest XML on DX, but don't let the price fool you. It's a great LED. I bought a bunch of them to upgrade some older SSC P4 bike lights.The tint is much warmer than the LEDs they replaced (see my uploaded beamshot photo). This is a big advantage for night riding, where a warmer light helps you distinguish trail features better. The larger die of the XML also results in a wider beam compared to the smaller die P4 when using the same optics. This is again of great help when trail riding. The original beams were a bit too narrow.The lower voltage of the XML also helps improve the efficiency over the older SSC P4, which can improve the battery runtime, and may help the light stay in regulation longer.I don't have the equipment to confirm if this is really a T6 bin, but it roughly doubled the light output of the lights compared to the original SSC P4 LEDs, so I am satisfied with the efficiency.
    If you're upgrading lights from older Luxeons or SSC P4's, you might need to use some shims to lift up the star into the reflector. Blank stars work great for this. Don't forget to use thermal paste or glue between each layer.
    A great LED at a great price. Get several of these to upgrade older lights, or build new ones!
  • Really bright fog lights.

    posted by LordPhoenix

    1) They are really bright.2) Have they own reflector, that creates concentrated beam.3) Looks waterproof
    In our country drivers should turn on lights even on daytime. These lights could save your expensive halogen lights and car will need less fuel - 2x3W LEDs better than 2x55W halogens. And these give you additional light at night time.Oh, and when it's foggy - your car wil be seen better than with halogens only.
    Good daytime lights.
