This is overpriced junk. It is being marketed as 9W but is actually 2.8W LED strip that you can buy in Delhi market for Rs. 20-80. See the proof in the video. When 12V is supplied to the tube the power shown in the power meter is 2.8W only. Also you can make out the low wattage rating of this tube by looking at the thin wires. See attached photo. Fake labelling as 9W to lure customers.
