  • Excellent!

    This is a phenomenal light strip. I screwed this onto the existing aluminum frame of an existing 30W fixture in a motorhome, using no heat transfer goop. The existing 30W flourescents drew about 1.5 amps. This 7022 strip draws about .8 amps, and is much brighter. I still used the plastic diffuser, and it helps. When I get around to it, I will be ordering more.
    The native voltage rating is perfect for a motorhome or car 12VDC. The actual voltage the strip is being fed is ~11VDC. Dealextreme offers other LED strip lights, these had the highest lumen rating, but now I want to try the others as well.
    Get several, get more light for less amps.
  • strong light source

    Round plate with 20pcs LEDs lit intense warm light. Luminous flux is about 70W clear bulb. Beam angle of 100 degrees estimate. She has a lot of heat, it is necessary to place the radiator. It can be screwed for the center hole. Isolate the screw, there is short supply pads. Covering plastic layer is soft to the touch. Rather put LED module cover glass. CAUTION: do not look directly at lighted plate, it hurts your eyes really shines a lot.
    It is an efficient light source with high power. I will powering 12W LED constant current cource cower cupply driver 300mA (SKU 81770). Lit perfectly.
  • Very nice

    Arrived in dark grey foil package. Good price. Color temperature of 3000K seems to be right, warm white light. Measures 10,0 x 0,9 x 0,3 centimeters (sorry for the metric system, I'm from Europe).Connection points on both ends work fine, might be useful.
    Aluminium heatsink might not be sufficient enough. I didn't measure it though.
    Very nice and original DIY part for projects.
  • Perfect for ceiling lighting

    Nice very bright light output and nice colour temperature. Leaning very slightly towards yellow it emitts a light similar to that of an incadesant light bulb. I have installed it inside a ceiling light that I purchased from Ikea (2.99). After stripping out the electrics the LED disc could be perfectly seated/Glued with themal paste) onto the metal structure of the light housing. This along with a 15w constant current regulator SKU186293 (Glued in place with epoxy putty) provided a perfect replacent for a 60w incandescent light bulb. It's been running for 3 months now with no over heating problems (Just the light housing to disapate heat) and provide enough light to fill my large bedroom.
    perfect replacement for incandescent light bulb.
    This is a high poered array of LED's housed on the same substrate. It gives of a lot of light (not to be looked at directly) and requires diffusion. Get this if you know what your doing and are handy with a soldering iron. You won't be disapointed
  • Really bright, very cheap

    It's really bright, better don't look directly at this running at 100% ;) Highly possible to be 1050lm as claimed. PWM dimming works fine.
    Cheap and good quality.
    If you use apropriate power supply and cooling it's really good choice considering price/quality.
