@califlowers
the lamps are two per box, they have 80 leds each, 60 are red and 20 are blue.
The wave lenght are red: 660nm, blue: 445nm.
The wattage used is 4.5 W/h so is very low.
They are intended for giving plants only the portion of light needed to grow and bloom.

Yes I found them on Amazon, and I read the reviews. It looks like it's a medium product, two lamps cost 20$. Everyone seems satisfied about these lights, since I don't have many pots and seedlings I guess they could work: the lights fit in a common table lamp holder.
The only "problem" if I can call it a problem is when it will be time to put them again outside and make them get used to natural light. Any experience on this? Also, I don't know how many hours should I let the lights on, I just want them to have light since it's almost impossible here (damned surrounding mountains and low winter sun)
Thanks everyone!
