The base of the 60watt equivalent LED light runs hot. Am using 2 lights in the kitchen ceiling. Is there any fire danger running the lights in closed, cramped space?
No, just short life.
How hot is it? Is it hot enough to hurt your fingers after a short moment of touching it?
The Philips basic bulbs get that hot but they are rated for 10 years or something like that.
It gets hot enough not to touch it only a few minutes after turn on. Great relief that only the life is affected. Maybe this is the reason the warranty is only 4 yrs. Thanks for response.
Incandescent lamps get a LOT hotter. Since LED lamps are more efficient, you can use a 60w LED lamp in a fixture rated for 60w incandescent max and still have some safety margin. A 9w LED lamp is way under the limit.
Totally escaped me how hot those incandescent lights were. Now I am not at all concerned about fire hazard possibility.
Wonder how cool those LEDs with rather bulky heat sinks are in comparison to ones without heat sinks.
I have some of each and externally they run at about the same temperature. I suspect though that internally the 99 cent ones would be hotter. Actually I know they run hotter because without a good thermal path there will be a larger temperature gradient from the source of the heat (the LEDs) to the outside of the bulb.
That being the case common sense says they should have different warranty.
In your post #154:
They are both rated at 16.4 years !? <===
Anybody have any ideas why the warranty is same?
Ability to heat sink well does nothing to reduce the total heat emitted; it only allows the bulb to shed that heat more efficiently. Given all else being the same the total heat seen by the fixture will therefore be the same either way.
It is entirely safe to use an LED bulb with the same output equivalency rating in an Incan fixture, although enclosed fixtures may reduce LED bulb life considerably. Incans can withstand almost any sane level of heat but LED’s may not like the same situation. But for this kind of price they’re worth a shot!

They may actually last longer than 1.8 years. Remember I proved, at least to myself, that the 2 pack of bulbs at 2 for $3.98 are the same exact bulb inside and out and yet they are rated at 4.57 years.
BTW, make no mistake, that is 4.57 years. Not 4.56 or 4.58. 
That just reminds me that I should take all of that stuff with a grain of salt 
As to my post #154 where a massive heat sink version of the 1100 Lumen bulb had the same exact lifetime as a version with no heatsink just shows that a lot of these printed specks are just a “copy and paste”
In another thread Found: $1 LED light bulbs at Dollar Tree I made a passing inference to this with this picture. 3 manufacturers of 3 different 40W equivalent bulbs, Osram, CREE and Greenlite. All three packages had the same EXACT specs.
450 Lumens
72 cents yearly operating expenses
22.8 years service life
6 watts.
That is not a coincidence, it’s “copy and paste”
We’ll probably be going to Lowe’s today to get a GE ground bar kit because HD doesn’t sell them in stores… so maybe I’ll find those 99¢ illuminators.
Edit: nevermind we didn’t go.
Went to do some plumbing work on a good friends house across town today. Parts were to come from Lowes so as we hit the door I mentioned the $0.99 lights and how we’d missed them (I’ve been sick a couple days, much better now). Then two displays chock full of them appear right at the front of the store :bigsmile: Another guy was looking at them as I explained Dchomak’s tear-down with these being the same as the “better” ones. I didn’t need many so I got 2, my friend got about a dozen as did the guy looking at the lights who joined our conversation.
Oh, and the plumbing went smooth needing only one extra trip to get a copper fitting I was going to reuse but couldn’t unscrew from the old regulator. 3 wins for me today, quite a lucky day indeed!

I picked up a dandy Utilitech headlamp at Lowes today for only ~ $12.00.
It is a single-mode ( which is all I ever want ) three AAA with motion sensing .
Wave on , wave off .
I went ahead and DC-fixed the lens as it was too spotty for my taste even though the reflector is heavily textured .
Bright enough for any close-up task and simple UI .
Wave on , wave off .
Edit : I bought 20 of those $.99 LED bulbs also .
.
If your watching the right sort of movie it could have a strobe mode as well!
LOL,
I started reading your post and when I got to the end of the second line I realized it didn’t rhyme. That’s when I had to start all over again 
An advantage of the 99 cents bulb is that they a very light weight. There are certain fixtures that I have that don’t like heavy bulbs.
Several of the Lowes around here is clearing things out. What they clear varies by store, or least WHEN they clear does. Here are some pics
Can’t read that? Price is 45 cents for CAT6 cables, 7’ long. They also had 14’ long CAT6 for 85 cents
The regular price was $8.98 and $16.98
I also found 2 spools of CAT5e cable at $3.75 each
I need to stop by Lowes on my way home and look for network cable…
OMG OMG OMG! GREEN WIRE CONNECTORS! 
:heart_eyes:
They are very useful and make any electrical box much tidier. Unfortunately they are always expensive.
Too bad the nearest Lowe’s is a little too far away… 
I wonder how long those prices will be around. Maybe they’ll survive until we are able to go to Lowe’s.
I got 5 of each length
I like the feed-through greenies with a hole in the center- they really make for a tidier box.
USA NEC now requires either a green wire-nut or a mechanical crimp sleeve tying all the grounds together in boxes with a single wire going to the switch or outlet ground terminal. An added non-feedthrough pigtail wire may go over the limit for wires allowed in that box while the feedthrough wire-nut won’t.
Phil
With a green grounding wire connector, in a box where you have a cable in and cable out (line and load) and a metal box and a device, you can ground everything with no extra pigtails. Just wrap one wire around the ground screw of the box, and then connect it to the other wire with the other wire going through the connector to the device. You actually only connect two wires but it does the same thing as having two pigtails therefore four wires.
