Just some friendly advice-

Before you rely on ANY safety goggles, please test them first. I have tried 3 different cheapo RGB safety goggles and all provided almost ZERO protection for (especially) the lower 445 wavelength and the 640 wavelength was still about 80% Trans.

PLEASE do not just rely on what the spec sheet and/or company tells you. ESPECIALLY if it was a chinese company. Just 2 weeks ago i had an "OD4" RGB safety goggle here to test for possible sales, 2W/445 hit them, 1.82W transmitted.

Just my experience. I am not happy with ANY of the RGB goggles i have tried out.
