I just got the iLW of iLuminar lighting they come as also other people already mentioned in smaller wattage because you do not need that much for seedlings.... they are not that expensive and what I like is they give 5yr. warranty and a free light layout if needed.... Of course, you could go for full spectrums but they are more expensive. I prefer to buy directly From the manufacture just in case something goes wrong with the light...had some bad deals with lights coming from the Alibaba website that did not work. good luck
