The product is good but expensive. Unfortunately it is the only lamp that works on the fitting.

5 / stars

Long lasting &well worth the money.

5 / stars

Well packaged items quick to deliver and large selection. Pricing very competitive will use again.

4 / stars

This lamp appears to be exclusive to Aurora, which may account for the relatively high price for what is essentially just a variant of a standard compact fluorescent lamp. My daughter's flat has ceiling lamp fittings that only take these bulbs, so I had to bite the bullet and buy a couple of them. I just hope they have a decent MTBF, otherwise the low running costs will prove to be insignificant compared with the replacement costs when they fail! On the plus side, they seem to be well made and they seem to provide full brightness immediately on switch-on.

1 / stars

I bought 11 of these in November 2014 for my kitchen. With minimal use only 3 of these lights remain working!!!. I believe the the problem with these lamps is that they run far too hot and the delicate electronics which are situated directly on top of the lamp are overheating and burning out. At the rate which these things are going, I would be better off with candles. really disappointed with these. 1 star is too generous
