Homedepot has a similar bulb for $19 (I see now you listed it). while nice I am not impressed. the lumens per watt is pretty low (lower than CFL) and its rather expensive.
YES I was getting GOOD bulbs for $12-$20 a pop almost 10 years ago. its called pulling out the sniper rifle and late nights on ebay
No that bulb is not it. I saw that bulb once and dismissed it as junk (inadequate heatsink if its even a real heatsink)
anything less than 70 lumens per watt I tend to avoid as not worth it. I am spending darned near NOTHING on fixtures and wiring. I am one VERY CHEAP SOB. when your downright moneyless you get very good at being CHEAP
those dinky bulbs will OUTLAST your expensive bulbs and produce the same light or close to it.
4 of them will give me nearly 300 lumens. MORE than enough for a hall way fixture. also by spreading the lights out you increase the "perceived" lumens quite a bit to the eye. that's also why I tend to try and go "bare" fixture so I don't waste lumens blasting the inside of a fixture.
That Phillips bulb? 12 watts 800 lumens. $40. your paying 5 cents per lumen which is cheaper than my 9 cents a lumen but you get less USABLE light per lumen and a bulb that WILL NOT last 20,000 hours.
Besides the kitchen I have yet to NEED that many lumens in a room. I run each bathroom on 9 watts. I had to cut that back to 5 bulbs or 7.5 watts because family complained it was "too bright" with 6.
you should see how bright my front door step is with just THREE of them. so for $21 for 3 lights and $3 (clearance at walmart) for the 3 bulb vanity fixture and $2 in "foam" to seat the fixture to the ceiling in the outside doorway I get more than TWICE the amount of light I had before with 2 13watt CFL's
We run it usually around 8-10 hours a night many times all night so figure average 10 hours (trying to think of a way to automate it but so far every way I come up with ACTUALLY consumes more power than just leaving the bulbs on 24/7
the CFL cost $1.25 a month to run or $14.97 a year so $15.
the LED's cost $1.55 PER YEAR to run saving me $13.45 a year meaning 100% ROI in 2 years. not bad at all. an ROI of 4 years is good this is 2.
I will consider them a failure if they do not last at least 12 years.
I think I paid $4 shipped each for the 5 bulb vanity fixtures in the bathrooms and $6 a pop shipped for the 6 bulb fixtures in the kitchen.
$40 is a LOT for a bulb to me. its why I don't have any of those. Can't afford them. especially with their VERY short rated lifespans.
that BETTER than 100 lumen per watt bulb is fascinating. I wonder how reliable the measurements are. but if that bulb can't hack it for 50,000 hours or more then its not likely worth it. and how much is it? (did not see a price listed)
One of the reasons I use so many. For example in the kitchen as you know I am using 6 2 watt bulbs. I have enough sockets for 12 of them. once I have the cash I will install the other 6 and then variac the power till they are 1/2 current brightness IE same brightness as 6 at full power.
they will last far far far longer this way. its possible to extend their lifespan essentially to infinity (IE longer than our lifespan) if the other components can "hack it" that long.
Here is the really nice bulb I have (I have 4 of them) they are 5 watts warm white I paid anywhere from $12 to $25 a pop for them)
the only one I have that has NEVER burned out yet. at least 2 of them have in excess of 30,000 hours of burn time on them already and they do not appear any dimmer or any change in color to date.
here are some bad pictures of it - sadly I CAN NOT find these bulbs any longer. I would swear its because they are "too good" so not profitable enough to keep making.
I wish I could get more of these. They are NOT the greatest for lumens per watt (got these before I really understood what lumen where) but for lower power bright enough long lasting applications they are #1 in my book.
Heck most of those bulbs you linked too (even updated ones) do not or barely exceed 50 lumens a watt. would be cheaper to run the $1 CFL I get from dollar tree (TRULY good CFL's by the way !! they DO appear to be holding up to their 12,000 hours life rating or close to it and a very nice warm white light too)
