  • KD-QP-9W-NBG E27 9W COB 1100lm Warm White Light LED Bulb (110~220V)

    KD-QP-9W-NBG E27 9W COB 1100lm Warm White Light LED Bulb (110~220V)

    Great light output, bad driver circuit

    posted by andremurari

    As light point of view it looks almost perfect.* Real 9W, real 1100 lumens - very bright!!* Made of one COB LED emitter (the better one - not a lot of smd, or high intensity output LED)* Low power lost as heat* Better E27 lm/w LED bulb sku at dx.com
    *You can easily substitute a 18W compact fluorescent (PL) or a 100W incandescent light bulb by this lamp (economizing 9WH or 91WH) . The Illuminance it´s pretty similar.*The light doesn´t look to have green light component as others reviews mentioned.*The circuit could be optimized to have a great power factor and low THD.
    If you intend to use several of these lamps I suggest you to use at least an third order LC filter to not cause EMI into your AC network. This kind of bad switching power supply can even cause abnornal nobreak trigger.

    Good product

    Plastic cover by solid. Connector E27 be standard, but plastic behind it be wide and must change bulb holder. Start is very fast and after two hour is could, about 40 degrees C.
    COB be interesting of design. I like it more than d standard SMD led. Be careful about Silicon cover - it easy to cratch. Dust from air hold on it and its visible and must be cleared sometimes.
    I dont buy it again, light is weak.

    This diode bulb build from high quality materials - metall, glass and plastic. Build quality is very good. I think that 600-700 lumens for this bulb it`s real. Bulb emits very bright light, feels like 60 watts incandescent lamp. Color temperature is warm enough.
    A bit expensive, but I think it's worth the money. We'll see how long it will last. Still much cheaper than common LED bulbs available in stone shops. One of the best lumen/watt ratio available on DX.
    Good replacement for compact fluorescent and halogen lamps. I would recommend to other people who needs eco bulbs with long lifetime.

    Good LED Lamp with 1100lm

    posted by AleX30003

    A small price. The technology of LED lamps is very economical - only 9W the light 1100lm. The light is bright, cool white - such as specified. Durable design, small size and large angle scattering.
    It was looking cool white light. I was looking for an LED lamp with a luminosity above 1000lm and found.
    All of the above: 9w and 1100lm, cool white light is bright. No complaints about the work.

    Unusual but good...

    Neat little bulb about the size of a thick whiteboard marker. Light output very good & almost perfect white. The arrays have a starfield effect - tiny regular brighter spots within the panels which is quite pretty.The bulbs are well made and are a bit of a change to the more usual multi led bulbs - they produce a more uniform light.Worth the price and worth using with transparent lampshades as the bulb itself is quite attractive to look at with the starfield effect. Recommended
    None really.
    Well worth the money & very good light output.
