Philips LED golf ball lamps, known as Lustre lamps are highly energy efficient using just 3.5 watts to replace a 25 watt golf ball, 6 watts to replace a 40 watt golf ball and 8 watts to replace 60 watts. They can be used to replace incandescent or halogen. Producing 250 to 806 lumens they offer a brighter and longer lasting alternative to a traditional golf balls.
There has been some negative feedback about failure rates on these bulbs, so this is perhaps a premature evaluation. We'll see how they do over time. But so far (after 3 days) so good! However, they are not as bright as I was expecting: they are significantly dimmer than 25W halogens.
For the office sputnik light Excellent quality
Great quality product! Please with the overall results, particularly as they work well with my old existing dimmer switch.
