Nothing quite says the 1970s like smoked glass. If that's the look you are going for, you might want to check out the Lily and Leah smoke glass pendant lights at BHS, which as you might expect, are at the more affordable end of the lighting market.
There are two versions of the Lily (pictured above), with just one Leah. The former is a choice of a short or more dramatic long 'drop', a mix of glass and steel with adjustable ceiling chain, while the latter is a teardrop-shaped glass light with chrome detailing and an adjustable cable.
As for pricing, the Lily are full-priced items, selling for £130 for the long and £90 for the short. The Leah is actualy in the sale, marked down from £120 to £59.99.
