7.5W LED Lightbulb, 40W Equivalent $9.99 Free Shipping orders over $50.00

In the bathroom we use 4 lights CFL 15 watt If I replace them with these at $9.99 each and my kids leave these lights on all the time. It will take me about 16 months or less to recoup my investment and I reduce the possiblity of mercury poisoning should one of the CFL's break which has happened.

This doesn't compare apples to apples. The 7.5W LED is a 40W equivalent, putting off 485 lumens. This 10W CFL is a 40W equivalent, putting off 520 lumens. According to your calculator, if you use 4 7.5W bulbs for 8 hours per day instead of 4 10W bulbs, then you save a whopping 23 cents per month! At that rate, it will take 14 years to recoup the initial $40 investment in these bulbs.

Also, how do you get free shipping? My shopping cart shows $6.29 shipping for one bulb or $2.99 shipping for 4 bulbs.

Edit: BTW, I use 4 13W CFL bulbs in my bathroom. 13W (not 15W) is the typical wattage for a 60W equivalent.

CFL's are not free and dont last 50,000 hours id say most dont last 10,000 hours by how many Ive replaced already. CFL also doesnt like being tuned on and off. You would replace a CFL 4-5 times easily at $2.50 each during the life of one LED bulb if CFL's actually made it close to 10,000 hours. That alone recoups the cost of the LED bulb.

Assuming this outlives just two CFL's the price difference is about $5.00 x 4 = $20.00 at roughly 40 cents per month saved 50 months but again an LED bulb would outlast a CFL five times over.

Right now I have 15 watt CFL's in there and its on the bright side so Im doubling down with less light and less wattage which should be just about right.

Having had a broken CFL in the kids bathroom where the kids toothbrushes, soap, etc are located Id say priceless.

I ordered 8 of them but your right free shipping is only if you order more than $50.00 I will update.

Tell that to the gubberment who wants us to use them and is slowly banning standard bulbs.

I suspect LED bulbs have a higher negative impact on the environment than a standard bulb too simply because of all the extra materials and processing required for their manufacture.
 
I've been getting my 40W equivalent LED bulbs from Costco for $8 a bulb. Unlike CFLs, they are instant on, produce a lot less heat, and the light is more pleasant. I replaced some 60W incandescent bulbs, and it seems like it gives off about the same amount of light.

Because standard incandescent bulbs take so much more energy to run, that means way more electricity used, which just doesn't hurt you moneywise, it also pollutes the atmosphere because much of the energy in the US is from burning coal. CFL are only bad for the environment if they don't get recycled correctly. In every other respect they are way better for the environment and your pocketbook. Don't listen to the big rich energy companies who want you to continue burning electricity when you don't need to. While CFL might have a momentary hesitation, not very much, you get used to it to the point you never think about. What I never got used to with old incandescents was them constantly burning out at the most inconvenient time.
 
What size LED builb is equiv to 100watt light bulb? Is it linear (i.e, if 7.5 is 40; does that mean 18.75 LED builb is needed ?). Also what is the normal temp of an incand. bulb? When I tried this a while ago I ended up with something that too blue 🙁 (was replacing a halgen lamp which I adore in terms of light - even if it used >>> watts).
 
I, personally, like how CFLs take a bit to heat up. Especially in the bathroom at night - they don't blind you with solar flair effect.
That said, I'm not spending $10 an LED bulb when I can buy CFLs for less than $1 all day 'err day.

An incandescent bulb is 2,700 - 3,300 kelvins (Source). If these are truly 3,000 kelvins, then it should have the same warmth of light.

As far as wattage per lumens goes, it seems to vary. Here's a 13W LED that claims to be a 100W equivalent. However, it produces 1075 lumens instead of the 1,750 lumens that a 100W incandescent produces. That "100W equivalent" is much closer to the 1210-lumen output of a 75W incandescent. I don't know much about LED bulbs, so maybe there's something with them that allows them to seem to produce more light with fewer lumens.
 
Hmm, if I'm not mistake, this is the everyday price for similar bulbs at Home Depot, at least this was the price last time I was there...

LEDs, being more directional, have less 'wasted' light than a regular filament bulb. or so i've read.

That's very interesting. I especially like the longer life of the LED bulbs. I've already replaced all my bulbs with CFLs. I'll have to do some more research on LED bulbs to see if I want to switch to them when the CFLs burn out.

This is what makes me laugh... Do this... NO WAIT. Do this...

OMG... Its good to see all the same feeling out there that I have.
I was startng to thing..... I am nuts.


The whole CFL's last 10,000 hours... YEAH RIGHT....

nobody recycles them correctly.
Nobody. This is why pregnant mommies aren't even allowed to eat Tuna anymore.

LEDs are the future. I can get on board with LED legislation but simply banning incandescents is lmfao stupid. Makes more sense to ban CFLs.

Define "wasted" light - for a spotlight, yes, LED would be better. But for general room lighting the directional light from LEDs can be rather, well, blah.
 
I wait for the local utility to have the rebates going at costo, then pick up 4-packs for $1-3 each pack (from the smaller 14 watt ones up to 30 watt ones in the big housings for recessed lighting fixtures). I must have 15x4 of various CFL's in my garage.

I'm not switching to LED's until they're at least $5 or under each.
 
given that LED is low voltage device, there surely is a step down transformer somewhere? if that is the case, are the inefficiencies of the transformer also factored in?
 
That is factored into the bulb rating. I have one that is rated at 6W and measured actually does pull 6W.

Power factor, well, let's not go there... 😛
