It is rather large, (I was afraid to get a little thing given the price) and rather good quality.
This is true of led, despite the made in china, and finishes are clean.
It has a hook to be fixed, but it is not especially convenient ==> 4 flexible metal rods are attached to the rear 4 corners, and join approximately 20cmet are attached together. And at the end of the joint hang a hook (round, and can surround a wholesale inning brushes).
Only notable absence is no ON / OFF button, but as I plug disconnected / unplugged every day, in the end it does not matter.
Taking it a little over a meter / one meter fifty, but that's just a hair. (Good quality, European plug with earth and rather thick cable, nothing to say)
For plants I can not really be on but I find it effective, they were the mouth and have recovered well and are even beginning to have buds! (I lunchtime branch is 23 hours)
Consumption level no idea but usually very acceptable as it is LEDs.
I highly recommend!
For delivery, rather slow (2 weeks!) But it comes directly from china, so this is explained.
It is well packed HYPER, (cardboard protected in another box even packed him in bubble wrap itself covered with a thick layer of thick black plastic film!
