Save the incandescent light bulb
Yea, yellow light seems old-school now. I love it still. I remember the times, only place where a tube-light used to be: the loo. Rest were all bulbs.

Its not old school, they are 90% similar to what the sun puts out which is what our eyes have evolved to see.
I don't care what the tech is to put out the light but yellow is a lot less harsh than white.
I use a program called F.lux on my laptop to turn the screen more yellow after sunset from the blue-white the CFL backlight puts out. Much more relaxing.
I have doubts even CFL's live up to their name, they lose their brightness over time and are dead within a year or so. The govt never got behind them or promoted them other than in limited ways.

I was on mobile earlier so couldnt post links.
So, here are the links to some of the LEDs I had followed on Kickstarter.
LIFX http://www.kickstarter.com/projects/limemouse/lifx-the-light-bulb-reinvented?ref=search
NanoLight http://www.kickstarter.com/projects...rlds-most-energy-efficient-lightbu?ref=search
The LIFX one is better in my opinion. They are accepting orders on their site now. If anybody wants to buy, get them in batches so that the order gets divided costing less than Rs. 10k (to evade customs
)

How is the above LED bulb?

These are the Power - LEDs. They usually get really hot. 3w means after about half an hour of usage you won't be able to hold it. So with any electric device that gets hot for long duration that means less life. Add to the fact that it's Chinese make.
If you want it for some project or DIY, then it's fine. But a strict no no for use in your house.
I hope that helps

Wasn't aware of that, I have ordered 3 more LED bulbs from Ebay to use in Bedroom and kitchen..
On the page, it is mentioned that life span will be < 20000 hours
I hope it is better than CFL..
Generally to avoid the heating issues heatsinks are used. But with those prices, it's tough to say if they have it or not.
I hope it turns out to be good. Do post here after you get them.

I had installed spot-light type philips LED Lights in my room
They are extremely cool, and don't make the environment hot like cfl's. Also the light are alot soothing to eyes in comparison to CFL or T5
Thanks...!
What is the price range. And what type should be used to replace a 100W normal bulb.
I have Philips 4w led replacing a 11w cfl/60w incandescent bulb cost is really high rs450/- per piece but it cannot be used for large space like hall. Not comfortable for reading and writing.

Its not replacement, you should measure how much lumens is needed.
If its living room, 10 lumens per sqft approx, bedroom 7-8 lumens like that.
Philips spot light led, the one i bought is 7w fire-rated one, and it gives 280 lumen output @ 2700k and 40degree beam, and its life is 40000 hours
Got it for 4200 per piece

Thanks a lot. Appreciate the inputs..!
A 25W CFL puts out about ~1500 lumens. Your 9W LED is probably putting out ~600 lumens.
Actually the 1400 lumen value is what they are able to measure from a finished product; so any losses due to the ring design are already accounted for. What you're talking about sounds more like the narrow beam angle of LEDs being more focussed and thereby appearing brighter vs the diffuse lighting of phosphor based lighting.
Each one will be suitable for relevant applications, although even the Philips' L Prize LED had phosphor panels over the LEDs to diffuse the lighting.
