People have trouble dimming LED solid state fluorescent lamps all the time. It's a very common complaint. You wouldn't experience problem dimming Mark X fluorescent ballasts with a proper dimmer either.I'd rather dim an LED than a fluorescent any day. Never had a problem dimming a dimmable LED. Just use a quality LED and a quality dimmer.

Lutron has two types of LED(SSFL) ballasts. Variable current or variable pulse duration each having their issues. Current reduction type suffer from serious color shifts as it is dimmed while pulse modulation type suffers from flickering or strobe light effect. When you look at tail lights of cars, you can see them looking like series of tiny dots when they're on low, but the tiny segments disappear when the brake lamps are activated. While this doesn't suffer from color shift, they fast pulsed drive also make it challenging for them to manage radio frequency interference and this type of dimming control experience meeting FCC Class B consumer device interference limitations.
WOW, I pay .07 so the payback isn't very fast but I use them every chance I get.I have loved and installed LED for over 5 years now. Put in the time to research the LED BEFORE you sell or install it for a customer. Dimming is tricky but only if you do not do the leg work and learn the product you are installing.
Always look at return on investment. We pay $0.23/kW here. Most new installations pay for themselves within 1 year. Retrofits can too, you have to look at the numbers. It might be a $700 pole light but the customer won't have to pay for maintenance and the $ savings start from day 1.
RAB puts a 10 year warranty on there fixtures! If an LED won't pay for itself in 5 years it shouldn't go in.
CFL and tubes are done... Welcome to the 21rst century.
Average for either. But commercial have demand meters so they can get slammed harder. I went through two years of bill with a bakery. Some months as high as $0.30/kWh. Others much lower. Overall average every time I have calculated works out to 22.7 cents. Only higher rates in Japan is the rumor I heard from PSEGLI but I haven't confirmed.Is that resi or comm
Over the lifetime of a fixture that runs 12 hrs a day, what do you think costs more, the purchase price of the fixture or the electricity consumption?Led's are being pushed, by tax payer money, and power company money that you pay in your outrageous monthly bill for using 100 amps.
A huge amount of perfectly fine lighting fixtures are being ripped down and destroyed for no reason other than a political agenda.
There was nothing wrong with the mercury vapor cobra head street lights they have wasted for these LED's that cost $700 a pop! Those mercury vapor cobra head street lights would work for 20 years without a problem, and if they needed repair the cost of the stock( Lamp and Ballast) was less than $100, LED's you must replace the fixture at the big price...:no:
You didn't lay out all the feasible options.Over the lifetime of a fixture that runs 12 hrs a day, what do you think costs more, the purchase price of the fixture or the electricity consumption?
That's the equivalent of 80 watts of LED, assuming 10 cents a KWH and 12 hrs a night and that your HPS only draws 150 watts, that luminary cost you $340 more to run than had you been running LED all that time.I have a 150W HPS in my driveway that's been burning for 14yrs, never changed a lamp. Not sure how long it was in service before I removed it from a job site.
Putting HPS, CFL and LEDs aside.That's the equivalent of 80 watts of LED, assuming 10 cents a KWH and 12 hrs a night and that your HPS only draws 150 watts, that luminary cost you $340 more to run than had you been running LED all that time.
When you put money in bank, it doesn't sit in a jar somewhere. They rent it out to someone else and that someone else have to pay a fee for the use of lump sum of money. If you have the money to pay cash for a large quantity of LEDs, you probably have cash sitting around that you couldn't find use for. Just keep in mind that you could have a *MUCH* higher ROI by using the money to pay off a higher interest loan in lump sump.It's 2 AM here so I don't want to do the math but you should buy the LEDs outright and put the calculated savings in a high interest bank account. :thumbsup:
So 14 years of that will make you smile.
They are fashion accessories, figuratively speaking. It's an advertisement and publicity expense.Then there is the Super Bowl thread... have to dig it up but they cut their consumption by about 2/3rds. Do the math on that baby and the NFL can easily afford another cheerleader.
