TGL Thunder
Grow Lights330W
The TGL Thunder is TodoGrowLed's four-bar fixture, and its spectrum is mixed on purpose. Each bar carries 144 Samsung LM301B at 3500 K for the full cycle, 72 more at 6500 K for a blue peak in veg, and 8 Osram Oslon at 660 nm for flowering.
Consumption runs 20-330 W across the dimming range at 2.4 µmol / J, over 120 × 120 cm in veg and 100 × 100 cm in flower. TodoGrowLed quote 450 g average and 500 g optimal. The frame is 78 cm by 68 cm and only 3.2 cm deep, 3.8 kg on its own and 5.5 kg with the driver, behind a Sosen IP67 supply and cooled passively.
It is not plug and play, and chaining several from one external dimmer needs a dimmer that is not included. Pulleys and screws are, and the guarantee is 2 years.
