I want to bring my olive tree over the winter without it loses too many leaves, I thought I could send him into a kind of standby by using the TT-GL20 Planzenlampe of TaoTronics. In fact, I do not so far succeeded, and even the neighboring plants, a Benjamin, two hydrangeas and a Japanese maple benefit from the plant lamp. All come new shoots and leaves. I have a simple switch connected in front which provides the plants according to light. In my opinion a top product and also in economical LED variant. The build quality is okay, do not see any danger zones, or the like. The case is sturdy enough to the lamp by hand screwed. The product dimensions are: 12.3 x 13.8 cm / the lifespan is over 50000 hrs / the installed LEDs have three colors: red 660nm 3x, 6x red 630nm and 460nm blue 3x. For the necessary warmth for me the floor heating, which the plants apparently also doing well. The packaging itself is a RoHS mark of conformity and the CE mark. Otherwise, the information is repeatedly made in China what I feel as well in so far all my purchases. Had no problems so far with China products and my trust in such a product is the same as in a product Made in Germany, Switzerland, USA or EU.
