7w led bulb Customers Reviews

  • Very good construction

    posted by renatotrindadelopes

    Well assembled, starts fast, one of the best color temperature that I have ever experienced on a LED light bulb. Neither "green" nor "blue". The color temperature feels like an yellow bright sunlight.
    I am using on a 127 V installation (Brazil).
    I have been using it daily (approximately 5h/day) for over 2 months and I would definitely recommend it to a friend.
  • Very good led array

    posted by pete1975

    Very good led component on these bulb led array. Surpass COB led array such as 181169 in both efficiency and total light output, with the same 3000k tint. Over 110 lM/W for sure at 300 mA drive current. Nice overall color tint.
    Three of those array should easily replace two 60W incan bulb in a dome light fixture retrofit. Each round pcb can be screw to the metal bottom plate of a light fixture for heat sinking. The dome glass act as a light diffuser. Could use two of them in series with 32-64V driver (190379).
    For those who want to try bulb fixture retrofitting with LED, these round led array offers an interesting starting point at affordable cost. Choose driver and number of array for the desired light output. Less wasted light than retrofit bulbs.
  • workplace bulb

    posted by vKreker

    - Good brightness. I think that analogue 75 watt incandescent lamp.
    - Big radiator = good cooling
    - Cree leds = brightness + energy efficiency + longevity + safety (unlike fluorescent)
    - if you have white ceiling, you can use it like a diffusor for bulb.
    in spite of imperfection i think that this lamp is better solution for workplace or garage.
    Use that bulb at home not comfortable.
    i think that modified construction of radiator may lessen diameter on 4 cm.
    At the same time bulb look cool. Designers appreciate.
  • Enough light for a small room

    posted by silviumc

    - low consumption- bright enough for a small room of 2x2 meters- instant full output, no warm-up required- frequent on/off switching is not detrimental to its service life like it's the case with CFLs- doesn't get hot
    It remains to be seen how durable it will be. I have mixed results with Chinese LEDs.. there's no telling which will last and which will fail in a couple of months.
    It would have been nice if it was a little less bluish.
  • Decent lamp

    posted by nachprod

    Low power consumptionVery acceptable build qualityLEDs are protected against damage and dust by a translucent coverColor temperature is actually quite warm, but see cons
    Power seems to be on a par with 40W incandescent bulb more or less. No 50 Hz flicker while used on AC, unlike some previous LED bulbs from DX.
    Decent bulb for a storage room or WC, perfect for country cottages, but maybe too expensive and definitely not too bright. I wouldn't use it to light up a living room.
