Hi there,
I know Roleandro light from Amazon.
I bought one before for my 0.5cmx0.5cm cupboard. I did choose a 300W, or supposed to be, and these supposed 300W were really not enough.
Plant grew and flowered and looked nice from distance but the flowers were really poor, no density and very small.
What is more surprising is those Amazon lights are not cheaper than the hydromars leds lamp.
Im not doing any adversiting here, just trying to make you invest in something with a similar price but better quality.
Hydromars is high rated here just saying that for 120€ you can have a led lamp TS1000 for Max Coverage:3 x 3 ft= 90cm x 90cm.
Hope it helps
