Thomas Watt LED (A+ rated) lamps are branded for distribution in France under an energy saving scheme. There have been 3 handouts. The first was 10 free, the second was 15 free plus €1 for a further 15. The last tranche, this month, is 25 for €1. Oddly you are eligible for each batch. It's not a wide choice, offering 9W ES 9W BC globe, 7W GU10 or 5W SES candle.
These run much cooler than a bunch of Ikea (A rated) LED ones I got in 2013, and use 1W less energy for the same lumens.
The GU10 has 11 LEDs and run at 96V DC/ 0.4VAC, although the HF component was too high to measure with a multimeter.
By comparison, the 10W Ikea ES globe (had 2 fail within a couple of months of use) have 44 LEDs and run off 30.7V set up as 4 clusters of 11 in parallel. It was the PSU that failed.
