Why is LED lighting still so expensive?

Oh I'm no fan of CFLs for sure. I was just hoping that LEDs would have made them history by now.

I recently had gotten a 10w Phillips LED lightbulb as per below


It replaced a 9w CFL I had and before that a 50W globe in a lampshade

I have 2 downlights on each side at 50W and I can say that this does a great job it's meant to be the same as a 60W but id say it's on par with a 50W downlight the light is nice and warm like the downlights and brightens up the place very well.

It did cost me $50 which is poo but I wish I could replace my downlights with 2 more of these it would fit perfectly in and would give you that soft warm feel you have when using warm white lights compared to white cfl's

Besides the funky shape (Which i quite like) it hasn't made me notice that i've changed to leds which is good and it will help with the power bill too which I like.

Although the tech is still costly I do think this has been worth the $50 and going by their costing of savings if used for 4hrs each day you would save $8 a year so 7 years for the investment isn't bad but then again I see it as $50 i just used on something and i'm not looking at making it back or why should i pay that when I can get a standard bulb for $2

LEDS have manufacturing issues, this is why the cost is high. 

They typically try to use good quality leds when making bulbs.  The problem is making a reliable led without flicker and without manufacturing defects is still very difficult.   The leds you find in most applicances, xmas lights, ect are low quality leds... generally 1 in 50 have a defect in some way and they lifespan can vary greatly from their suggested lifespan.  Also there is a cost of circuitry.  Yeah the leds themselves are realitively inexpensive, but the ac to dc conversion and power regulation circuit you find in a lot of bulbs isn't. 

I don't think led bulbs are going to catch on until they make leds lamps, aka a lamp with all the power regulation stuff in the base, so you only have to buy the leds.

Almost 2 years on my 10 dollar bulbs.  No failures or degradation in any of them.  I think I have 10 total though some are used a lot more than others.

I'd probably own more but the other half of my house is running on CFLs that have been good for 5+ years.

Another issue with CFL is that you're not supposed to turn them on and off with little time in between.  When you turn them on, they are supposed to stay on for 15 minutes before being turned off again.
