Pro-emit’s DIY-M-KIT 2 long Series 300W is a modular, passively cooled LED grow light designed for 100 x 100 cm grow spaces. The 3-channel design uses Samsung LM301B diodes (5000K and 3000K) for the white base spectrum, complemented by Cree XP-G3 deep red (660 nm) and Cree XP-E2 far-red (730 nm); a blue peak around 440 nm supports vegetative growth. Four 75 W boards deliver a total input of 300 W and an output of about 840 μmol/s at 2.8 μmol/J. Each channel is 0–100% dimmable via individual potentiometers; Mean Well ELG and LCM drivers are included. The assembled fixture measures 80 x 45 x 8 cm, weighs 10.29 kg, and is rated for 50,000 hours. Tested PPFD maps cover 100 x 100 cm at 30–60 cm hanging heights.
