Double Ended Lamps
The DE (double ended) grow lamps connect to the power line via 2 connectors. The glass is made of quartz and are 5cm shorter than SE (single ended) HPS bulbs.
DE lamps are 25 to 30% more efficient than a normal single-ended HPS lamps. This is confirmed by Utah State University (UT, USA). HPS Double Ended lamps have a wide choice of voltages from 120 to 400 volts, and are typically designed to work in 750 or 1000 watt pre-wired systems.
Example of the efficiency of HPS Double Ended lamps, micromoles for 30 cm2:
1000w HPS single-ended lamp (Philips): 1550 micromoles
1000w HPS Double-ended lamp (Philips): 2100 micromoles
