This review is from: TCP LED GU10 5 Watt LED Spotlight, White (Kitchen & Home)
Customer review from the Amazon Vine Programme (What's this?)
I replaced a more conventional GU10 in a line of ceiling mounted lights, the bulb fitted my light holders/settings perfectly.
The light value (colour) is good moving out of the normal yellow ranges.
It lights immediately, no lag, a factor that often confuses those used to the old type of bulb.
It consumes little electricity, much better for those who want to leave on the light for long periods (over night?)
It appears to be much cooler in operation, see above.
It is advertised as have a long life, ? less refitting, normally at night.
The main factor against is its cost, does this outweigh the convenience? How often are you having to replace more conventional bulbs, how much electricity do they use.
