Safety[edit]

There have been some reports (link in French) by reputable organizations that LED spotlights might not be safe, especially for children. It would be nice if the article addressed this problem. Joelthelion (talk) 17:45, 19 April 2015 (UTC)

Cold temperature operation?[edit]

I have found from personal experience that a 60 watt cfl bulb in an outdoor fixture did not last more than 3 months during the winter even though it was turned off in the daytime. A fluorescent fixture in my uninsulated attic would not start in cold weather.1archie99 (talk) 16:12, 22 November 2014 (UTC)

Better lamp[edit]

Impressive! This Philips bulb is much better than the one in the table. I was going to add these numbers

2.49 8.5 800 94 2700 80 10,000 5 48 58 63

but the "limit 10 per order" pushes me not to. At the amazon price, though, it still beats the other bulbs by a significant margin. So should we replace the extant Philips bulb, using the Amazon pricing or the special deal at The Home Depot? Calculation for last row (Total cost per 860 lumens over 20 years @ 13 cents/kWh & @ 6 hours/day) : (40*13/11*1.02+4.97*2)*860/800=62.52 (40*13/11*1.02+12*2)*860/800=77.63 --Elvey(tc) 15:35, 7 May 2015 (UTC)

Wikipedia should not be a parts catalog nor a sales brochure. Although we may list "typical" prices for things it should not be specific to any vendor, "special deal" or not. Jeh (talk) 16:21, 7 May 2015 (UTC)
Agreed; let's update it and go with the typical pricing, thus:
6 8.5 800 94 2700 80 10,000 5 48 72 77
--Elvey(tc) 04:55, 16 May 2015 (UTC)
I just reverted a change that replaced the typical pricing (which I updated a few days ago) with the special deal pricing - despite the above consensus to use typical pricing (which already makes this product the price leader), and made what seems a wrong replacement of 2 with 5 in terms of unit counts per 20 years.--Elvey(tc) 21:22, 24 May 2015 (UTC)
FFS! 4 bulbs needed for 20 years @ 6 hours/day, AFAICT. Not 5. WTF? --Elvey(tc) 06:04, 30 May 2015 (UTC)

Well, with your revert we now have the situation where different bulb types with identical 10,000 hour lives have a different number of bulbs to last 20 years, which is simply wrong! Also pre-revert we had the happy situation that all the long-life bulbs were replaced to give an identical 50,000 hours of life. Please rv your revert to get the table back into this happy situation.
