led power module Customers Reviews

  • good product

    posted by fnflores

    good quality product, great luminosity (please take care, do not see LED directly), easy to use, it is applicable for any Arduino LED project, it comes with a standard packing.
    Recommended for high luminosity LED projects (I did a Christmas light for home), also to test any Arduino library works fine!
    Use it! it is fun and really easy to use!
  • Bright little lights!!

    posted by Tourniquet

    These things are BRIGHT! I installed them as indirect deck lighting under my railing on my deck and it looks awesome! I used a 30 watt waterproof transformer and wired them all in parallel. Very easy to install. I even put one in my pool for night time swimming!! They are waterproof after all!!
    I was originally going to install them as recessed step lights but after seeing how bright they were, I decided not to because it would flood my back yard and neighbor's house with too much light. I'm thinking of using my extra ones on my car maybe as fog lights or under carriage lights. you could even use these in your home for under cabinet lights or even flush mounted in your ceiling. Overall I am VERY pleased!!!
    For a waterproof product, you really cant beat the price on these. They have the ability for multiple uses and provide an ample amount of light
  • Works nicely, but skeptical regarding connector

    posted by Highlord

    Small device, screw holes, easy to adjust voltage. Nice range, seems quite reliable.
    Keep in mind that I'm not experienced in electronics, nor have I tried many alternatives. If no one else comments on the connector, it might just be me doing it wrong.
    I don't regret buying it, I'll surely keep finding uses for it.
  • small dc-dc converter

    posted by nuralist

    The device was bought for powering Cree xml diode to limit current. The device have Voltage and Current regulation. My diode takes 3 ampers of current so I had to use little radiator with a thermal grease on the LM microchip, without it temperature was more than 100 C and LM chip protection had tripped. After i've used heat sink everythink became OK)
    informative specification
    good deal
