Fragile Don't seem to last five minutes if they get knocked, I've put 10+ in lead lamps and any bump they are broken. Normal use in the home I'm sure they will be fine. 29 Jul 2015
cant hold a tourch up to them Great item at a fab price Not much you I need to say 24 Jun 2015
Great while it lasted Gives a lovely clear light. Unfortunately I purchased it in August 2014 to use in an outside, PIR light so not on very often (< 1hr a night)!and it has already blown. 18 Apr 2015
Great value Absolutely great value and a brilliant bulb. Give you good light due to it being clear glass. 26 Mar 2015
