I can't find any information on the CRI (color rendering index) of these particular bulbs, but Cree was making a bulb a couple years ago that was rated over 90, which is generally considered excellent. If these are comparable, they're a fantastic deal, particularly given the warranty.
Note that 80 is the minimum legal to qualify for Energy Star.
i use one of these to walk my dog. it's ridiculously bright and it's laughable when you see someone using a 'normal' flash light which basically just looks like someone using a zippo lighter to light their way. bought 2 for the office and 1 for the car too. mine use regular AA batteries not the expensive high voltage rechargeable ones. edit: this comment is about the same cree LEDs except in flashlight form.

personally i think you are being an asshole... he just forgot to mention he was talking about something else in their product range. It is in that context, still on topic.
Note that I did not downmod him, but at least 3 other people did. I was warning him before his account got hellbanned.
But I guess you see prefer to see bad intent.
Wow, that "auto-aligning" of the (supposed) current slide to my screen is incredibly annoying.
If they'd just asked 5 people for feedback.
This is huge if only because a LED bulb company finally put its warranty where its mouth is. Every other bulb, ie. the expensive Phillips bulb, only gives a 3-4 year warranty I'd definitely give this a try @ $10 It's also dimmer compatible which is a big plus for me with X10 control, CFL cannot dim. If this bulb does not operate for 10 years (based on 6 hours per day / 7 days per week of normal consumer use) from dat…
This page has GOT to stop moving!! GRRRR. Who decided this was a good idea?
I guess I don't know what is preventing me for having a bad experience, but I guess one of those 3.

Are there any lightbulb engineers on HN that can confirm that lightbulbs are indeed, so to speak, "made to fail"? Or is it actually really difficult to make a long-lasting lightbulb?
Off topic, but am I the only one to find the automatic scrolling very annoying ? Don't move the page on my behalf.
Talking just about the incandescent ("classic") light bulb's life...isn't its life limited by the policy of "planned obsolescence"? http://en.wikipedia.org/wiki/Planned_obsolescence Are there any lightbulb engineers on HN that can confirm that lightbulbs are indeed, so to speak, "made to fail"?

You can buy "rough service" light bulbs: http://www.bulborama.com/Turbo-Life-20-000-Hour-Light-Bulbs-...
They are, of course, much more expensive per-unit.

no mercury hazard - you don't have to vent your house and worry about mercury exposure if a bulb breaks.
In my entire life I've broken exactly 1 CFL - and I was a kid at the time. And you don't have to vent your house, that's an urban legend. The mercury is elemental mercury which isn't very toxic, and extremely poorly absorbed on top of that. (The toxic mercury is organic mercury. Some elemental mercury will be converted, which is why people worry about it - but it won't be converted in your house.)
