We deliberately only provide PPF values, not PPFD values. The PPF value describes the light output of the lamp for which we are responsible. This value varies depending on the chips installed, their number and the driver settings. Although we do not believe that the PPF value is a good indicator of the quality of a lamp (see above), it has become common practice to provide this value and our customers expect this from us. The PPFD value, on the other hand, describes the actual amount of light at the measuring point and is influenced by many factors that we cannot control. Different measuring environments, reflections and measuring methods lead to varying values. When we issue PPFD values, this is usually only done for specific purposes and with precise information about the measuring method.

This is due to our philosophy of "quality over quantity". The PPF value of a lamp indicates how many photosynthetically active photons the lamp produces. Dividing this value by the energy used gives an efficiency value. The "photosynthetically active" range of light extends from exactly 400nm to exactly 700nm. This means that all photons in this range are counted, while others are ignored. Some manufacturers focus on high efficiency by using only red LEDs at 660nm, for example. These achieve high efficiency values ​​above 4.5 µmol/J, which looks great on the data sheet. However, pure red light has a negative effect on plant growth. Therefore, they mix in blue and white chips, which lowers the overall efficiency. We go a step further and replace red chips not only with blue, but also with UV chips, even though these do not have PAR efficiency. We do this because we know that UV (and Far-Red) are extremely important for the harvest result. In the end, beautiful flowers are more important than impressive spec sheets.

There is no simple answer to this. First of all, you have to consider if you want to illuminate a certain area with a lamp (e.g., 60x60cm with a GCx-4), you have to hang the lamp at least high enough for the light cone to reach the entire area, which in this example would be from a distance of about 15 cm. It is also important to remember that LEDs emit a certain amount of heat. Depending on the ventilation, it may therefore be necessary to maintain a certain minimum distance due to the heat.

Yes, a plant will grow based on the amount of light it is on, not the spectrum. Although our "solo" range uses a "bloom spectrum", it can still be used for growth. However, the growth will not be as compact and squat as the GCx-4 in pure growth mode. We are the only manufacturer to offer a growth mode at all. If you use a solo lamp for growth, you can expect about the same growth result as from our competitors.

No, these lamps are only dimmable. Their spectrum corresponds to the flowering spectrum.

No, please always connect all the strips and screw the connections tightly. Otherwise, the lamps could be damaged.
