    Hi,

    a bit old topic but I would like to add that lumen is based on how bright a light source is to the human eye. For plant light PPFD is more relevant, that is the amount of light that is useful for a plant. These LEDs produce 100 μmol/m²/s, for comparison: for vegetative growth 300-600 is recommended, for blooming 600+.
    I have an E27 växer bulb, from what I could find on the internet it has some regular white LEDs and some additional red ones. So they are not as effective as special grow lights and you would need to put at least 3 next to each other to get a meaningful amount of light.

    The 46.5cm long Växer (L1519 a.k.a. 703.231.10) lists 15X0.9W 16W of LED power. Where 15 times 0.9 watt = 13,5 watts DC. Before the AC to DC conversion that results in a AC power draw of 16.0 watts.

    The 31.5cm Växer (903.231.09) will contain 9 (3 times 3: 2 white and 1 red LED per opening) LED’s of 0.9W = 8.1 watts DC or 10 watts AC.

    Hi woom,
    I wrote to IKEA UK support in this case and they answered: “PPFD refers to the amount of light your plants get per second and is measured in μmol/m²/s. This lamp provides an average of 100 μmol/m²/s.”

    Recently i found some new information o UK IKEA site. Now there are informations, that the smaller cultivation lamp set has 550 lm, and the bigger has 900 lm. I wrote an article on this topic on my site. Its in polish, byt you can use google translate.

    I hope it would be useful for You.

      Hi Kamil,

      Thanks a lot for that info! I feel kind of proud I guessed almost correctly 🙂
      So, for the record – it’s 550lm @ 10W / 900lm @ 16W.
      Would be nice to know the light spectrum, but I understand it’s a commercial grade appliance for amateurs.

      Nie muszę używać google translate 🙂
      Some good ideas on the website – it could be a fairly popular resource if it was in english – I think it’s worth a try.

    Assuming it’s as efficient as LEDARE that would be about ~800lm, suitable for 0.06m^2 of plants.
    Not the best bang for buck. But it can as well be a different type of LED’s and produce twice as much light, so I’m guessing here. IKEA should put that parameter in description 🙂
