Myth busting: Lumens
You can see what they've done, is incorrectly used the 'Cree Product Characterization Tool' which is not a specification, but a spreadsheet based on mathematical approximations.
In fact, even 200lm/W is unlikely for system efficacy except for super high end lights. Take the LM301B with peak luminous efficacy of 223lm/W at 65mA, for example. Why then does the HLG 550 v2 only have a system efficiency of 171lm/W?
Including ultraviolet (UV) as well as infrared (IR) and far-red waves. These wavelengths don’t factor significantly into photosynthetic rates, but they do affect plants, and in some very interesting ways. It’s important to note that UV and IR lights should generally be operated independently from primary lights, and run for short intervals in your garden.

What Are The Benefits Of Switching To LED Grow Lighting?
LEDs are currently at the forefront of indoor horticulture and vertical farming. Growers now have the ability to digitally control their light spectrum to create the optimal environment for maximizing harvests.
- LEDs use significantly less energy
- LEDs emit little to no heat reducing cooling costs
- LEDs last 6 to 10 times as long as HID or HPS equivalents
