Cree Light Bulbs
#1
On a recent episode of Dr Oz, he mentioned using an LED light bulb instead of other lighting to help fall asleep. He said an LED bulb would not disrupt the production of melatonin in the body, like other lighting will. As a day sleeper and night shift worker, I was interested. So, my search for LED lighting has begun.







I remember when the first CREE flashlights came into the country. It was around Christmas time, I had just received my yearly job bonus check, and it was White Elephant time! I decided to get myself and my White Elephant recipient a new CREE flashlight! I barely made it in time, they were that new. That flashlight is my still my work EDC pocket light!







Since then, the CREE LEDs have just gotten better and better. Its not only CREE, there are other terrific LEDs out there too! It seems, the CREEs have developed to the point, where they make an acceptable alternative to other low energy light-bulbs. Anybody use CREE light bulbs or have any recommendations or experiences?







Guess I could check out the knowledgeable folks at candlepower forums, but I like the perspective I get here! [url="http://www.candlepowerforums.com/vb/forum.php"]http://www.candlepow...om/vb/forum.php[/url]









An Amazon search seams to indicate Homedepot as the cheapest place to buy. [url="http://www.homedepot.com/s/cree%2520lightbulbs?NCNI-5"]http://www.homedepot...ghtbulbs?NCNI-5[/url] What ya say?

LEDs are a very cool technology, and like you, I think the LED bulbs have reached a point where they are worth checking out. I don't have any experience with them yet, but I can tell you to watch for what shape the bulb is (or maybe you don't need to). Some of the newer bulbs are smaller than a regular lightbulb, some are longer/bigger, and some are a weird shape. I have a lamp that fastens to the bulb itself. For now, I keep using regular lightbulbs in it. I've seen places where new bulbs stick out of the socket too far (or are just too big to fit). It got me because you normally didn't think about bulb shape and size - just wattage.





From working a night shift before, I had to put heavy blankets over the windows to keep the sun out, and I found that Christmas lights gave a pleasant warm glow without being too bright or awakening.





Good luck with the night job - I found it very unnatural.

I bought a 100w equivalent LED at Home Depot for $20. A little expensive, I thought, but I like it. It seems brighter than any compact fluorescent 100w equivalent, and the color of the light is fine. It goes on instantly to full brightness. If the prices come down, I'll probably buy some more.



I also bought a 60w equivalent LED that was on sale at Home Depot for 3 something dollars. It's disk shaped. I haven't used it yet, but I'm looking forward to trying it, since I like the first one I bought so much.

I checked his website for LED light bulb recommendations. So far, he lists few options, but one must remember if he doesn't use the heck out of something first, he doesn't recommend it! Also, he seems to key in on low light output bulbs.

I still need to check my local Home Depot. My girlfriend's electric bill was thru the roof this month. She runs out door lights all night, all around her house. Home Depot does have LED flood lights.

I know it was many years ago, now (seems like it was just yesterday).... when I was in electronics classes in school, we calculated that a 100 watt lightbulb running 24/7 would cost less than a penny per day to run. If her electric bill is super high, I'd look at larger things first - air conditioning, heaters, electric stove, refridgerator/freezer, big power tools, etc.



LEDs are still a great way to go, though - they cost a fraction of what bulbs do, last pretty much for ever, don't get hot, can come in colors, etc.

Appreciate the insight Motman! I will look into that first.





I went to Home Depot yesterday and purchased a 60 watt equivalent Cree soft light bulb for $10 The 40 watt was $14! [url="http://www.amazon.com/dp/B00JCV594K/ref=asc_df_B00JCV594K3143788?smid=A2NF2CO8O10X7X&tag=pgmp-788-97-20&linkCode=df0&creative=395133&creativeASIN=B00JCV594K"]http://www.amazon.co...ASIN=B00JCV594K[/url]







A quick check indicated the Daylight bulbs were cheaper than the Softlight bulbs. The Phillips bulbs were by far the cheapest of everything! But the package did not indicate what type of LED was used.







A quick checked indicated by several factors, except for price sometimes, the CREE lightbulbs are so much better by far, as stated by others. The price difference outweighs the superior difference between the two. I will not be buying anymore florescent light bulbs! Due to the cost factor, I will slowly change to LED bulbs.





My 60 watt Cree was much brighter than expected! Can't wait to try the 100 watt model! These things appear to go on sale from time to time, so I will keep checking. Motman and george were spot on with their info!

We bought a couple of the Home Depot LED bulbs as an experiment. So far, they run cooler than the incandescent bulbs, and don't flicker like the CFLs. Talked to my electrician (conservative hippy type). He likes the low draw of the LEDs, if you can get over the initial cost.



For a home replacement bulb, I wouldn't get too caught up over the specific type of emitter. Look at the overall performance.



CCrane has a good overview of various LED bulbs on their site.

I completely forgot about C.Crane! Been doing business there for years!





I agree on the cost, but I like the durability factor of the LEDs. IF I drop an LED, it will not be as messy as the other bulbs. They seem better adapted to outdoor use also. The cost will slow down my conversion to LEDs though. Research seems to indicate CREE is the way to go, except for maybe low wattage bulbs and bulbs on sale.
