"Gardeners' requirements for their lamps can be just as different as the lamps' requirements for their gardeners." With this sentence, SANlight presented its previous ECO/EXPERT setup. The system has now been replaced by the new EVO LEDs, but the core statement is still true.
The differences between a PRICE-PERFORMANCE and a HIGH-END complete set are primarily in the power density that you achieve with the included LEDs. The PRICE-PERFORMANCE setup is aimed at "normal" growers and is also great for anyone who has just started growing indoors. The sets convince with an excellent price-performance ratio and do not place any special demands on the gardener. So you enjoy the benefits of high-quality SANlight lighting without having to worry too much about your plants. Compared to a sodium vapor lamp with the same lead, you also save 50% electricity.
HIGH END sets, on the other hand, require a little more attention; The LEDs that you get in such a SANlight package have a lot of power! While this can noticeably increase your yield, it also pushes your plants to their limits all the time (too much light can also be quite demanding for plants). So they are in a constant state of stress and need special care - they don't take mistakes as easily as you might be used to. If you trust yourself to be able to trade the HIGH END setup, you will benefit from beautiful, large flowers. The power saving compared to HPSs is still a good 35% here.
