TGL Star 100

The TGL Star 100 is the bigger of TodoGrowLed's two round COB fixtures — their own page calls it the older sister of the smaller one. It draws 105 W and carries either a Cree CXB 3590 or a Citizen CLU48 CRI97 chip depending on the spectrum, behind a MeanWell XBG 160-ABOL driver, cooled passively with no fan.

TodoGrowLed rate the veg area at 90 × 90 cm, dropping to 80 × 80 cm in flower, at 2,3 µmol / J. Spectrum options are 3000 K, 3500 K and 4000 K. Stated production is 145 g average and 150 g at best.

It is 18 cm high and 15 cm across, weighs 3,2 kg, and is plug and play with a 2 year guarantee. The narrow gap between the average and optimal yield figures is unusual and worth reading as a sign of how tight TodoGrowLed expect the results to be.
