Two things I noticed when I first took these out of the packet was the build quality and weightWeighing about 50grams each by my rough estimate they are suoer light. Because of this It makes it ideal to go in a goose neck Lamp that I have which doesn't have a particularly strong goose neck meaning any heavy bulbs make it curl downwards.But because of these it no longer does thisAlso unlike most really light cheap bulbs these actually are really bright as I'm sure you'll have seen from other reviewsThe build quality is exceptional.The screw fit is perfect and although a tiny bit fiddly to first insert...one set up its perfect!The bulb bit is my favourite bit.Plastic Is an insulator meaning that in theory the bulb would get much hotter internally...but because it is led it does not get as hot meaning the plastic is same to touch and it reduces weight whilst it is at it!Led bulbs also do not need warm up time unlike the outdated halogen ones I use because once warmed up they are nice and brightThe led light is just as bright if not brighter without the need for warm upHowever it does not give off the same slightly yellow lgiht which is good for the melanoma which helps to send you to sleep and invoke endorphin (or so I've been told) which is a shame because I have reasonably light sensitive eyes and if I turn on this lgiht because of the bright white light it gives me a small headache sometimes...very rarely but doesn't help if you've had a tiring day!Other than that the only other thing I hope they could improve is Making it so that they change colour through using a clap or a switch.I know it wouldn't be too useful but whilst they are using leds they might as well make use of the multi colour leds meaning you could have mood lighting too!!!But alas that has not happened yet...OverallBuild quality fab!Weight is amazing!Efficiency I have not noticed but assuming is goodNo warm up time neededBut...Can cause a rare headache to people who have minor light sensitive eyes!Other than that rare occurrence they're great!  Read Less
