Wonderfully bright! Really good and bright bulb, totally flicker free and an excellent colour for working in all day with no tired eyes. No real warmup, slight blue tint when switched on, but this quickly goes to white/daylight. Vast improvement over incandescent daylight bulb, and highly recommended. Erik Pearson -
Excellent product Both the 100W and the 60w biobulbs are excellent for working in 'daylight' on jobs needing true colour matching,eg photography. Bright clear light, comes on immediately, no need to warm it up.Colour cast looks a bit cold and ghostly at night, less suitable for living rooms. Virginia Lee -
