This seems excessive for a pre-revenue company of Lightwave's size. According to Investopedia,
The median compensation for members of private company boards of directors was $44,850 in 2021, according to a global study by Lodestone Global.
and
According to the company's 2021 proxy statement, Walmart’s compensation program for outside directors offers base compensation of a $175,000 annual stock grant and a $100,000 annual retainer.
and
Apple’s non-employee directors each receive approximately $250,000 worth of restricted stock units per year, which are granted at the annual shareholder meeting and vest on Feb. 1 of the following year. Non-employee directors also receive an annual cash retainer of $100,000.
Lightwave directors got more than directors at Walmart and Apple! To be fair the options are not given every year, but it still seems excessive.
