^What? Why?
Are these using Luxeon LED’s? I experimented with them before. Bright as fuck but they give off a lot of heat too…which is an obvious sign of inefficiency.
I doubt it because I would guess these lights don’t even hit 90 degrees.
You realize that INCLUDING the operational savings it will take you 3 yrs & 11 months to BREAK EVEN mike?
Buffalo has about 12hrs day average sunlight (yearround average).
You’ll get 4 yrs 7 months out of 20k hours of lighting.
Meaning that every 4 yrs & 7 mos you’ll have saved / made $18 as opposed to using an incandescent 60w longlife.
Do you want me to do the math for the CFLs?
I don’t leave them on 24 hours. They are rated for 10 years at 8 hours per day. I use them less than that. What will electricity cost in 5 or 10 years?
edited for later math
Thanks for the plug Newman. I don’t have a store but I work with the 3rd largest wholesale light distributor in Nevada who has a warehouse. I can have things drop shipped anywhere in the country also. Check out the website www.msissl.com to look at the product line. There are a few bulbs not listed on the site yet that I have available. PM or IM me for any more info.
Incandescent $31.80 per year
Flourescent $6.89 per year
LED Geo bulb $3.97 per year
^This is based on 4 hours per day which would give it a 20 year life.
That is at least $436 in savings over incandescent.
The bulbs I sell have a 10 year life span before they start to lose their brightness. The 10 year figure is based on a 14 hour per day usage. Just FYI.
heat is an issue with all high-powered LED’s.
i’ll see if i have any cuts of fixtures we have recently used, massive heatsinks and all
The bulbs we use run @ 60 degrees. That’s a main advantage of the ones I sell over others. Your A/C doesn’t have to fight them.
Mr Smoss, try to follow me through some basic math. I’ll use your stated figures of 4 hours per day.
4 hours per day multiplied by 365 days = 1460 hrs a year.
20,000 hours / 1460 hrs = 13.7 years
This is the service life that we will compare ALL three formats too.
LED $120 cost, 20k hours, annual cost $3.97
CLF $6 cost, 8k hours, annual cost $6.89
LLI $1.20 cost, 2k hours, annual cost $31.80
LED: 13.7 yrs x $3.97 (cost) = 54.53. 54.53 + 120 (purchase) = $174.53
CFL: 13.7 yrs x 6.89 (cost) = 94.39. 94.39 + 18 (purchase x 3) = $112.39
LLI: 13.7 yrs x 31.80 (cost) = 435.66. 435.66 + 12 (purchase x 10) = $447.66
So, over the service life of 20,000 hours:
LED over Longlife incandescnet will save you a total of $273.13
$273.13 / 13.7 = $19.94 PER YEAR savings.
LED over Compact flourescentwill COST you a total of $64.14
$62.14 / 13.7 = $4.53 MORE PER YEAR
I’m shocked that YOU of all people got CAUGHT UP IN MARKETING HYPE.
The advantage the LED bulbs have is their lifespan. Some of the stuff I’ve looked at works for 50-100,000 hours. The savings is when you replace the Flourescent bulb 3-4 times before you replace the LED again.
^ Not according to the data (mike’s manufacturer’s rating) and that pesky math.
Google any of the figures I’ve posted, and use mike’s LED price of $120 PER BULB
ONE HUNDRED AND TWENTY DOLLARS
When CFLs cost $5-6 per bulb
and
LLIs cost $1-2 per bulb.
Well those are Mikes LED price haha. Who pays $120 a bulb? Also, the ones I sell are guarenteed to last 50k hours before even losing 1 watt of brightness.
The life is 30,000 not 20,000. Where did you get 20,000? Did I say that? If I did it was a mistake.
Thom, i am NOT redoing the math for you, but yea, those will work out MUCH better.
again…that is usually for just the diode, and doesnt take into account lumen depreciation.
you have seen complete lamp packages with a rated life that high? with a decent percentage of output? and a warranty to back it up?
Yes sir I have. I posted the website to look at. The track lights we sell come as the unit that mounts right to any existing J Track.
