Why no cree?
Great post Douglas!
Are you sure your dimmer switch is approved for those specific LED bulbs? The makers publish lists. Humming and only dimming to half brightness are tells that it's probably not. Some LED bulbs are made for incandescent dimmers, but many (if not most) are intended for dimmers intended for LEDs.
Also, they do make LEDs that turn orange/red when they dim, but they're expensive.
No, I don't know, to be honest.
But it's not for lack of trying. The GE bulb had a website to go to to check for dimmer compatibility. The bulb I bought was not listed on the site.
I'm having similar problems with Philips. I'll be damned if I can find one reliable source for dimmer compatibility. This list:
seems to indicate that their 13W BR30 bulbs are compatible with my dimmers - at least I think so, because I think I have the 600W Diva, but it's possible I have the 250W. Also, the bulb pictured is definitely not my bulb and no model number is listed.
This is a hurdle for widespread adoption of LEDs, IMO. I'm not a home improvement wizard, but I am a good google searcher, and I haven't turned up anything definitive, and no, I don't know my dimmer model number exactly. You used to just go buy a lightbulb. Now you have to have a contractor's license and an internet connection, and even then you're partly guessing. My wife couldn't even begin buying an LED bulb.
I didn't look at any Cree bulbs because I didn't see any at the Depot. I was looking in the soft white section, and as I look at their site, it appears that they don't make a 2700K flood.
The Depot did have a house brand looking bulb, I think it was EcoSmart or something, but I took a pass on it based on other things I'd read on here about sticking to the name brands. These are expensive enough that if they fail after 2 years, it's a real pisser.
I don't think you should mix and match incandescents and LEDs on the same dimmer switch. That might be your problem. I actually bought dimmers to go with the bulbs, so I didn't have this trouble; but I did notice that when I had different makes of LED bulbs on the same dimmer I ran into problems with flickering and humming. If it comes down to it you can get a new dimmer switch for your LEDs. You can move the incandescent dimmer to a room that previously didn't have one (if you have one).
And I agree it's a pain, but what choice do you have? Uncle Sam is on course to ban even the 65-watt incandescent bulbs in a couple years. My house was laid out for 100w bulbs, and LEDs are pretty much the only choice other than halogen PAR-type bulbs that don't work well for a number of reasons.
Also, I wouldn't rule out home depot house brand bulbs. I think most of them are made by Feit, which is a good brand.
Edit: that's Lowes. Nevermind. Home Depot's are apparently made by "Lighting Science Corporation," who also makes some others.
All good thoughts; unfortunately the only way to know for sure is to buy a bunch of bulbs and try!
Still, I appreciate the advice and I will do some more experimenting. Will report back later.
Ha, I was just googling the same thing and found the same article.
An option to consider: I'm 99% sure those are the same bulb, and they're very well reviewed. Coscto supposedly sells them cheaper, but I don't know because they don't exist around here.
If its humming, that sounds to me like either a problem with the dimmer (as suggested, it might not like mixing bulb types) or a defect with the bulb.
Is it a 60hz hum or something else?
I've found through experimenting that LED do not like an odd bulb on the same circuit. Some of the digital dimmers can be adjusted to work in the range that the light works in.
Wondering if you guys have any insight on the pull-out resistance of good 3.5" cabinet screws into pine studs.
It's a lot. I have a chin-up board mounted with 4 of these screws, and it holds my 215 pound weight just fine.
All of the research I've found is for screws that engage about 3/4" and even at that depth they seem to be very capable of handling this task.
I'm thinking of replacing my carpets with hardwood flooring in my condo with the intention to sell in about 3 years. I like the look of hardwood and would like to enjoy it for a few years. I have been looking at some walnuts and maples in an effort to get a light colored wood that would increase the perceived size of the space (Dining room, kitchen, living room - 750 sq/ft). I am leaning towards maple as the salesman says that its less humidity sensitive than walnut. What are yalls thoughts about the curb appeal of light woods? Any other comment/suggestions would be appreciated.
