Philips Premium
Price: £14.50 Beam rating: 42
There's no sharp cut-off, and that made life tough for this plus 30 per cent bulb, which is the standard offering from Dutch multinational Philips. One of the German-built bulbs didn’t perform as well as the other in the pack, although both delivered a relatively low hot spot, which ultimately held the product back in our key 75-metre beam test.
