Quite a bright virtual filament LED bulb, at least the equivalent of a 100W incandescent. I have not seen a BC base lamp of this output, for the price, elsewhere. Buy four for free p&p. Does not weigh much more than an incandescent, so suitable for Anglepoise lamps etc. Also good for standard lamps where you don't want most of the light going up at the ceiling?. Also being sold on the Maplin Ebay outlet.
