  • Bright

    posted by l4dzk

    I am using them for landscape spot lighting. Very bright white light. Seems much brighter than my neigbor's 10 watt halogens. Seems waterproof. The wires are pre-leaded and are about 6 inches longs. Beam is relatively wide. Seems to hold up to rain for 2 days now.
    I have not tried to submerge these and run them for any period of time yet since the wires are only 6 inches long so I have not figured out to light for my pool, but I may attach them to the rim of my pool above water.
    I bought ten and they all work. I am planning on buy at least 20 more for my front and back yard.

    ***Good item for do you own portatile charguer for much less than buying a new one in shopping centers***
  • 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.
  • Very good size

    posted by rebelfw

    The size is very good, small enought to fit inside the walls electrical boxes.Do the job its supposed to do.
    Should have been identificated the AC and DC side.It have a + and - in one side, that identificates the DC side, but I think for novice users, it could be tricky.
    I used it to power a wireless relay and it works pretty well. You better not put this near your bed though. The noise will annoys you.
  • 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
