Title photo led lamp with curved filaments. This form of led strands to achieve a uniform illumination and to make the lamp a little more lights up than conventional filament lamp. On the left, the radiation pattern of the conventional filament lighting "candles", right — "candle" with curved filaments.
Such lamps while it is impossible to buy, but in the spring they will be on sale.
Filament lamps taking over the market — they are simple, cheap, look good, have a very high efficiency (up to 125 LM/W). Filament lamps appeared in the range of all the leading manufacturers — OSRAM, Philips, Gauss, Camelion, Era, X-Flash, Navigator, ASD, Smartbuy, Uniel, REV, Jazzway, Feron, and others. Ikea is silent. :)
Wholesale price for 4-watt filament "candle" in China has fallen to 60 cents, and led bulb prices are falling rapidly.
Finally frosted filament bulb. This allows you to use them not only as decorative but also for conventional lighting. Frosted "candles" and "ball" produces Lisma 45 mm, in the range Uniel is Matt "pear" "candle" and "balls", but Uniel matting more transparent and threads clearly visible. Frosted filament lamps appeared on the OSRAM website, but live I have not seen them yet.
Philips appeared dimmable filament lamp that allows you to adjust brightness from nearly zero and the light pulse.
Other manufacturers with demirbeyli filament lamps is not very well — the same Uniel dimmable sells "candle" pulse is under 100%.
Philips has released a series of diminuem bulb DimTone, the color temperature change when dimming from 2700K to 2200К, simulating yellowing by reducing the brightness of the incandescent lamp.
X-Flash has released a series of led lamps 12 volts. These lamps come in handy for tourists, cottagers as emergency lighting from the battery, those who build the lighting system, powered by solar panels.
Many manufacturers have begun to produce very powerful led bulb with E27 base. Have Nanosvet appeared lamp 18 W with luminous flux of 1,600 LM, in X-Flash lamp 22 W with a luminous flux of more than 2000 LM.
And I continue testing the lamp for three days has tested more than 70 pieces. published
