Newly Enlightened
My first Advanced Lumonics EarthLED (specifically the Evolux Sh 13 Watt, 3000K [100 Watt Incandescent Equivalent]) arrived today. Cost me just under $89.00 w/shipping. Comparing it with the 100W incandescent it replaced (a Sunbeam Soft White - rated at 1120 lumens) it certainly seems bright enough.
First impressions are:
-it's got a noticeably cooler color temperature
-doesn't light the ceiling as well as a regular incandescent (has no up, only down with some spread to the side - spread is more like a flashlight with the lens taken off)
-allows for really good color distinction
-Plastic "bulb" that protects the LED is frosted (sort of) - has a non-transparent appearance probably with a two-fold purpose:
spread the light more evenly and soften it (take the edge off just like in "soft" incandescents) This could probably be described better. I'm sure some of you could help.
Here are the stats I pulled on it, along with some energy efficiency calculations I made:
EarthLED EvoLux Sh Specifications and Dimensions:
• Light Engine: CREE® LED Light engine
• Power Consumption: 13 Watts Max (12 Watts Typical)
• Input Voltage: 90-277 V AC (Worldwide Capable)
• Luminous Flux: 1075 (Cool White), 1000 (Warm White)
• Color Temperature: 3000 K (Warm), 6000 K (Cool)
• CRI: 75 – Cool , 80 – Warm
• Beam Angle – 180 degrees overall
• Operating Temperature Range: -4°/ 113° F (-20°/ 45° C)
• Operating Humidity Range: 20%/90%
• Lifespan: > 50,000 Hours (MTBF)
• Construction: Flame Retardant Plastic, Active Thermal Management w/Fan, Shatterproof Lens
• Base Types Available: E26/27/BC22
• Physical Dimensions: Overall Length – 4.44 in (113 mm) Diameter – 2.55 in (65 mm) Weight – 6 Ounces
• Cost to run for one year* – $3.80 Calculated assuming 8 Hours a day operation, 365 Days a Year with $.10 KWh Electricity Cost
-Pulled from the EarthLED site: http://store.earthled.com/collections/frontpage/products/new-earthled-evolux-sh
Now, some calculations (go easy on me guys, I'm fairly new to this stuff):
Average incandescent 100 Watt bulb
-$1.00
-1700 lumens or 17 lumens per Watt
-1000 hours bulb life
-Costs $29.12 - $43.68 per year to run (based on 8-12 hours per day, 7 days a week, 52 weeks a year usage)
-Needs replacing 3-5 times per year (based on 8-12 hours per day, 7 days a week, 52 weeks a year usage)
Advanced Lumonics EarthLED (specifically Evolux Sh 13 Watt [100 Watt Incandescent Equivalent])
-$88.98 (w/standard shipping)
-1000 lumens or 76-77 lumens per Watt
-50,000 hours LED life
-Costs $3.79 - $5.68 per year to run (based on 8-12 hours per day, 7 days a week, 52 weeks a year usage)
-Needs replacing every 17-11 years (based on 8-12 hours per day, 7 days a week, 52 weeks a year usage)
Conclusions
Total cost of purchase and use of Earth LED 13 Watt at 12 hours a day for 11 years - $151.46
Cost of purchase and use of Incandescent 100 Watt bulb at 12 hours a day for 11 years - $528.98
*All electricity costs based on $0.0001 (1/100th of a cent) per watt per hour
BTW: If you think I'm crazy for purchasing an $80.00 incandescent replacement, I should tell you that I've recently joined a team in my organization that's sole purpose is to save our organization money. They asked me if I'd head up LED lighting research. I figure, if I am going to recommend LED lighting replacements I might as well have at least one at home to try. (Didn't want to be hypocritical) With calculations such as the ones I just gave (and that's for a single bulb!), and knowing that right now these guys (EarthLED) have ready-to-go fluorescent replacements, I think this could save our organization 10's of 1,000's of $$$.
