in Asia you will likely find a wide variety of lamps from different manufacturers. Mr Aqua makes their own lamps which are slim and bright and only now entering the u.s. market. The problem i find with led lamps there is a lack of product information. To grow plants, knowing the particular color spectrum would be immensely beneficial but many are not labeled, often times they are geared towards reef tanks using the blue leds. Visit the lfs and see which ones they have on display with plants. i beleive that will be a clear indication on which ones work and do not for this application.
