  • Indeed more than 1000 lm

    posted by Morsk

    I am buying (and testing) LEDs for many years now, but they rarely meet the spec. This one does! And the price is really extremely low. Good results in my one week life test too.
    I see many reviews asking for supply proposals. Some hints:- Never use a fixed voltage supply as the LED voltage changes with temperature, so your current may go everywhere.- You can choose a supply with a little over rating as it is quite easy to reduce the current by changing the current measuring resistor (the most prominent one on the board).- This one from DX works fine with 900mA, 10W, SKU: 42745.I have done a sort of life test for this product. Had it on for a week at 11W while measuring current, voltage and luminance. I did not see any change. Note I used a (bit overdone) heat sink with a rating of 1.8K/W, so with 11W just 11x1.8= 20 degrees above ambient.
    I hope they will be available soon again.
  • Let there be light

    posted by DaveDaring

    Very small and compact indeed once combined with the B22 to E27 adaptor still took up less room than than a conventional filament light bulb or fluorescent fitting
    The quality of the light is great the warm gold quality is much easier on the eye than the harsh white you can sometimes get from LED fittings
    Combine the compact size, the low price with the quality of the light emitted you have a great product.
  • Does not fit all R7S armatures

    Very low power consumption compared to conventional R7S filament lights. The leaflet claims 13 Lumen per Watt.
    Not dimmable, will flicker instead of dim on lower voltages but then it didn't say it was dimmable ;)Take good note of dimensions, a minimum of 15mm clearance is needed underneath the connectors heartline. I had only 12 or so. It was possible to modify my lamp but then it turned out it was not dimmable. I'll use it elsewhere where both issues are no problem.Warm white apparently is a matter of taste. I think it is more white than warm but at least it's not blueish white.
    Could be great if your light fits the ramature and you don't require dimming
