Transatlantic<\/a> recently asked about a new IKEA LED lamp, the LEDARE with 1000 lm.<\/p>\n

It comes as a quite big globe (diameter 95 mm) with an E27 socket, an electrical power rating of 16.5 W and is supposed to be dimable!<\/p>\n

Transatlantic commented on the high quality of the warm-white light output and wondered if these were still constructed in the same way as the previous LEDARE<\/a>, which features a combination of white and red LED chips inside.<\/p>\n

Now I was able to buy one of these lamps at my local IKEA store in Uppsala, and promptly had a look under the hood. <\/p>\n

Again, the LEDARE lamp makes a solid impression from the outside. It is quite heavy because of a strong metal base, which also serves as a heat dissipator. The plastic dome is glued onto the base, underneath you will find a circular array of 80 small, warm-white SMD LEDs. No red LEDs involved. The LEDs are mounted on an aluminum-base circuit board, in 8 parallel groups of 5 LEDs each. All 8 groups are connected into a series string.<\/p>\n
