Lighting 30W - 5000lm?

[Hybrid]

They are selling LED lamps 30 watt claiming to give 4000-5000 lumens.

Is this just a scam or is it possible?
5000 lumens using 30 watts is 133-166 lumens per watt and have to be a good deal if it's really working as claimed.

Anyone tried to grow with this kind of low wattage LED's?
If they work as claimed these LED's should be perfect for small grow rooms, having 1 LED per plant or 5000 lumen per square feet

Its actually a fairly plausible number for high efficiency LEDs. Generally those blurple screw in bulbs are pretty bad and I cannot really imagine anybody trying to create a high end grow light going that route so I would not buy them myself. There is a lot more to LED lighting than just lumens. Lumens only measure quantity, not quality and some spectrums are easier to drive then others - so as always YMMV.
