Time to buy LED lightbulbs.

[deanrd]

USMB Republicans have been critical of LED bulbs insisting they are two expensive.

95% of the energy used by an incandescent bulb is converted to heat, the remaining 5% is light. Run a 60 watt incandescent bulb for 10 minutes and then unscrew the bulb by hand. What do you feel?

Run an LED bulb that's comparable for 10 minutes and then unscrew the bulb by hand. Feel any heat at all?

LED bulbs last 50 times longer.

Just saw an add on TV for four 60 Watt comparable LED bulbs for $4.99..

That brings the cost of LED bulbs in line with the cost of incandescent bulbs. As LED bulbs are used more and more, the cost will continue to decline. How many lights in your house?

New "Light Recycling" Incandescent Bulbs Could Outperform Energy-Efficient LEDs

But all is not lost. Scientists are figuring out a way to recycle the heat which might eventually make incandescent bulbs more efficient.

Im a CONSERVATIVE who replaced all the bulbs in my house with LED a LONG time ago. I won't tell you what I paid. Just always thought they were the best.

 

[jon_berzerk]

what a nut-tard thread

who dont like led

--LOL

 

[ZZ PUPPS]

I no longer buy incandescent but I use my old supply in the winter since they do give off heat, thus capturing the heat and using it offset the heating bill.

While you have that LED Bulb in your hand, feel the weight. There is a separate power supply and a MASSIVE heat sink as part of the design. It's not that LEDs generate no heat. They generate heat over a smaller area thus making it necessary to use extensive materials to "fan out" that heat or cause the LEDs to die prematurely. They do generate somewhat less heat. Which leads to your 2nd "misconception"..

All that "heat" from an incandescent is not wasted. In the right season, when the household has the HVAC on heat cycle --- every lighting Watt going to heat --- REDUCES the load on the HVAC system. It is NOT wasted. And far more lighting is used in the Fall/Winter when days are short.

This effect is so significant, that it is reflected in the Energy Efficiency calculations for HVAC sizing. Mostly LED lighting can increase the SIZE of the HVAC unit used.

converted every bulb in and outside the house,except those on the garage opener motor to LED's at least 5 years ago and havent had to replace any yet.....

It's wasted heat if it a vaulted ceiling...where no one lives...

So a person's choice of lightbulbs determines their political party affiliation?

I use candles made from possum fat...Yeah I run an animal shelter with a spa, fat just rolls off after a good workout..

. I use incandescent and neon...Some of the damn light fixtures that are fancy use the overpriced light bulbs and are multiple socket...making it even more of a cost..

Not really because HVAC adds the circulation necessary to distribute the heat. Vaulted and high ceilings usually have fans because the HVAC heat will do the same thing.

dean as usual missed the posts from lefties here saying the same thing....to expensive....but as far as i am concerned they have paid for themselves as long as i have had them going.....

 

[playtime]

yep- we have about 1/2 LEDS & 1/2 florescent bulbs... our town hall takes the florescents for recycling & as they go we are replacing them with LEDs. the only incandescent bulbs we have are for the dining room 'chandelier'. cannot find LEDs for it yet.

 

[flacaltenn]

I've done LED bulb designs for huge commercial/industrial fixtures. Not really fond of having all those separate AC/DC power supplies exist in every socket. It's a reliability and a safety issue. If the design is not properly certified/tested -- really bad things can happen.

In addition, when I come home, I don't want "office colored" lighting. Man has adapted to the warm glow of a burning fire. And the stark white lighting -- even from the "warm" colored LEDs just doesn't cut it for me. Makes my bath/bedroom look like an Operating Room.

[BulletProof]

You can buy generic brand 60 Watt comparable LED bulbs for about a dollar each, in multi-packs.

Those light-reflecting incandescent bulbs will never be competitive with LEDs.

It's unfortunate that cheap LED bulbs are handicapped with the need to convert 120v AC to low-voltage DC. But, in theory, LEDs can be designed to run directly on 120v AC. Even better, it should become a thing for people to have low voltage DC in their homes, as all electronics are native to low voltage DC. And, for those generating power at home, low voltage DC is also native. It's a huge waste of energy to convert energy to high voltage AC and then back again.

In the energy efficient future, high-voltage AC should be obsolete.

Only stupid people avoid LEDs.

Only stupid people would risk their homes buying $1 LED bulbs. There is so much that can wrong in there, that $1 bulb should be a big flashing warning sign.

And yes -- at some point, new homes will have separate 12 or 24V DC supply bussing for lighting and charging portable devices. But the AC mains will still be there.

LEDs are inherently DC devices. They are DIODES. Don't like AC. There are few "novelty" AC LED products. But you can't get efficient power thru them.
