Just some thoughts.
My job is 35% LEDs. I didn't try to sell any LED products here. I have nothing to gain from this. I do love LEDs.
Good LEDs are great. For a small amount of light, or light concentrated in a small spot.
For warrenty, if you import them yourself, you have to pay 2-way forien shipping. Not worth it. It is very expensive. My last importation ended up over $11 per pound (about 7 Euros per kg) for 600 pounds. It is also very difficult to return something made in China, back to China... I have heard almost impossible.
Shipping to the USA would be about $50 for 1 bulb. Each way. Best guess.
Also, they claim mcd is only 1200 maximum per LED in their LED section. The lowest is 250mcd. Good LEDs are expensive, and much brighter (8,000 to 10,000 mcd). The only decent LED chip with a mcd over 10,000 have a narrow viewing angle.
For an LED bulb at 220VAC in something at this cost, the regulation is just a resistor. The lowest current comsumption would be 0.020 amps. That is about 4.5 watts. Any decent 5 watt CFL would be about the same current, a little more, but many many times brighter than these LEDs.
Anyone with enough of the math skills, time, and patience should compare mcd and viewing angle, with candella or candle power. CFLs win for an area light. LEDs win for a night light or reading light. Nothing beats good LEDs in a properly designed flashlight.
