A typical t8 is inThe same 2900 lumen ballpark.....and 32 watts.
So at 28 watts for the led......you are saving 4 watts. Simple math....(not accounting for power factor or anything).......is you save 4 watts per hour of run time.
50,000 life of a led bulb.....will save 200,000 watts. Or 200kwh.
My electric cost me about 12 cents per kwh. So 50,000 hrs to save $24.
So based on my electric rates of 12 cents.....20,000hrs run time is about the break even point per bulb.
On a side note.....it is nice to see that they are pushing the lumens up to at least match that of t8's.
For the longest time, the claim was that they use half the energy. Which was correct. But they only put out 60% of the light. So you had to use more of them.
Lumen for lumen.....LED's are NOT 50% more efficient. More like 10% more efficient.
People ask me all the time when they walk in my shop.....and see 10 6- bulb fixtures and 5 4- bulb fixtures...."surprised you haven't switched to LED to save money.
Well.....I like it bright. If I wanted to save money and get less light like LED's, I'd just take half the bulbs out.
But like I said, nice to see a led option that at least matches the lumens of a standard t8. Puts things a little more in perspective now that lumens are equal. And a 32w t8 vs a 28w led......certainly not the 50% savings that led proponents keep touting
