Our trusted advisors Karl and George both have off-grid cabins, where every watt they can eke out of their solar panels makes the difference between reading by headlamp and being a bit more civilized.
So, naturally the weekend email thread was on the latest and greatest compact fluorescent (CF) technology, so-called cold-cathode bulbs. George was particularly excited about the bulb pictured here, a 5W 300 lumens (about 40W equivalent), available for a cool $10 each.
If you’re monitoring your electricity usage you probably already know what a big impact installing traditional CFs can have on your home electricity. These bulbs typically save about $40 per bulb over their four year life — a net value of about $30! How many products do you buy that actually build value?
Even if you are filthy rich, the environmental incentives are high. Changing a standard 75W bulb to a 20W compact fluorescent will save 500 lbs of coal and 1300 lbs of carbon.
The new CCF bulbs are even more efficient, typically boosting efficiency 4-7x over regular incandescents. George has installed these in his cabin and notes additional advantages:
- Dimmability: the CCFs are dimmable, with no hum.
- Size: CCFs fit in all fixtures, unlike some long or snow-cone CFs.
- Longevity: CCFs last up to 25,000 hours.
The last one is particularly relevant for a busy consultant like George. Even if George makes it up to his cabin every weekend, the bulb will last for 96 years. Perhaps the manufacturer, Litetronics, should take a cue from the marketing team at Patek Phillipe.
You never really own a cold compact fluorescent by Litetronics…
…you just pass it on to the next generation
George, here’s hoping you outlast your latest light bulb purchase.
