Ufnortunattly the picture you can see is not good and you can't see "climate" that is in the kitchen, at real effect is much better. One this kind of LED bulb is made up of aluminum plate 16cmx16cm that is move away from ceiling (1cm) for better cooler, to this board is screw aluminum PCB palte with 3 worm LED diodes 1W by CREE company in PLCC casing and under plate there are blue diodes the same mark, for better esthetic. Diodes are powered by my own conventers

Converters are powered by transformer power supply. Soon i'm going to design converter that is powered by 230V grid. Thanks to that I can get better efficiency and smaller dimensions, of all lamp. One bulb is made up of 3 LED and can give 210 lumens, what means that 6 bulbs in 7 square meters of kitchen is too much so i need to make some brightness regulation.
