1. the price
2. no battery operation
The second point is more serious for me. Nowhere in the photos can be seen, with the lamp needs to be plugged in the nasty white cable. It would be much more innovative to have a charging station and to operate the lamps with a rechargeable battery. Zumindeset optional. LEDs consume little power and the lamp could safely light up for several hours with the battery. The applications would then be limitless. You could even take on in the garden and put it on the lawn when grilling.
So you have, unfortunately, always struggling with perhaps 1.50m long white cable with thick power supply that has the aesthetics of course away because of all the product photos. I'm still thinking whether I'll keep the Hues, because the clutter bothers me.
