Which grow lights provide the best PPFD?

HPS Grow Lights

However, one of the biggest disadvantages of HPS is the super high heat production, which in turn puts pressure on plants. This is one of the reasons why those who seek the maximum PPFD output increasingly do not believe in HPS. In addition, the orange / yellow wavelength of HPS spectrum is low. Although HPS is becoming increasingly unpopular. This is a good choice for those with a budget, but serious growers are now looking for other technologies to produce the best results.
