Work in your grow room at night, without waking plants up.

Green LED Head Torch helps During flower, it’s imperative that light-loving fruiting annuals are not disturbed as they can revert to vegetative growth, slowing your progress. At the very least, when plants receive light during their night period, they go through undue stress which can lead to aborted flowers and fruit.
Greenlight does not stimulate chlorophyll, so plants cannot ‘see’ it – that’s why the green LED can be used without interrupting the night cycle.
As indoor gardeners, you may need to view plants at night depending on their light schedule and your regimen – e.g. foliar feeding or simply routine maintenance before continuing your schedule - it's not always possible to visit the garden during the day.
