Vivosun is obviously trying to be direct competition with the spider farmers with their new LED models. The specs are very similar. They both are using the Samsung LM301 diodes. SF is using the B model and VS is using the H model. From what I have read they are essentially the diode but the B is the original and the H is the “horticulture” version with very minor differences that really only amounting in a little more efficiency.
The question is, is there more differences between these lights then meets they eye? I have a couple SF and the SF-4000 is preforming comparably to my HPS 1k watt at a fraction of the draw, which makes me very happy with it. However, can you really justify paying 25% more for the SF when the Vivosun VS-4000 is Soo close in spec. Has anyone done a side by comparison? Do you see other important spec differences that may have more weight then I’m giving them?
