The same deal is true for competitive bulbs.
NICE PUNTO SWITCHER FULL
That 60 watt Wal-Mart bulb, when operating base down in open air and not even using a shade, has its internal LED case at 85 ° C, the absolute upper end of what is considered “safe” for full life expectancy. Within an LED bulb the internal generation and distribution of heat is such that it “desperately” needs access to cool surrounding air.The fact that it has that metallic housing is irrelevant in restricted air. This is not at all the case for a 40 or 60 watt-equivalent.
As noted, folks assumed that anywhere you had the 40W or 60W incandescent, you could screw in the CFL.
NICE PUNTO SWITCHER UPGRADE
Fixture makers learned early on that if there is a socket, many consumers will assume it’s good for any bulb, which is not expressly warned against.īack to our story:Turns out that the consumer’s assumption is not valid: that the LED bulb is just another upgrade like the CFL. Why ? Because if a consumer installed an incandescent bulb of higher wattage than recommended, “bad things” could happen in the light fixture. Probably 95% of all UL approved recessed down-light fixtures have, for decades, incorporated simple inexpensive “thermal cutouts”.
What’s not to like as prices keep coming down? It follows then that consumers now have a similar expectation for LED versions, with even longer life and greater electricity savings, dimming, and even better color consistency. The hundreds of millions sold globally suggests they provided pretty much what was expected. In most cases, however, CFLs have proven to be a good return on investment, lasting much longer and sharply reducing electricity costs. Maybe it would not allow dimming…maybe it was slow to warm up… maybe the color consistency was not as expected… and some “mongrel” brands have proven not to last as long as was thought. Perhaps time for a reality check or two… meaningful for the average consumer, who has no little or no clue about CCT, CRI,or heat sinking as they buy light bulbs to simply put light when and where it’s needed and doesn’t need it to be iTunes compatible.įirst some facts:For decades consumers have come to assume (a reasonably valid assumption) they can buy almost any CFL and screw it into any place they previously had a 40W or 60 W incandescent bulb. Prices have dropped sharply, appearances have become somewhat standardized and dimmable versions are becoming commonplace.So now most of the media and blogosphere time is spent in infinite speculation about the pros and cons and timing of when we will have such bulbs with built-in Wi-Fi, color tuning, smartphone gadgetry, retail pricing at the $1.50 level, and the pros and cons of the versions at Wal-Mart versus those at Lowe’s and Home Depot. Most readers are aware of all the recent hoopla regarding 40- and 60-watt LED versions of standard 40- and 60-watt bulbs.
