Are these bottles strong enough for beer? They seem a little lighweight to me or is this because of their smaller size?

A green beer bottle, for example, does not absorb green light, it absorbs all visible wavelengths except green. This is an important distinction; since green bottles do not absorb green light (520â550 nm) this wavelength passes through the glass and catalyzes the reaction that results in the dreaded skunk nose! Clear and blue glass bottles produce the same result.
The color brown is a mixture of red, orange and yellow wavelengths. These colors range from about 580â700 nm. This means that brown beer bottles absorb the shorter wavelengths that damage beer. Brown glass is pigmented with iron oxides, among other metal oxides, and these various forms of iron absorb UV light over a wide spectrum of wavelengths. In a nutshell, brown glass absorbs the visible and UV wavelengths of light responsible for skunkiness. Brown glass is also used to store other light-sensitive products, such as medications and film developing reagents
