Just changed over to LED lighting

Recommended Posts

My "Otoko" T8 led died the other day after almost exactly 1 year of "normal" living room use.

I also discovered that despite saying it has reduced RF interference compared to florescent tube....it seems all its RF interference is in the FM radio band resulting in only 2 stations with high enough power to cut through the hash.

I went for daylight because all my fluorescents were daylight.

I got sick of the 'check the connection, change the starter, change the ballast' routine every time a lamp failed. Not often to be sure but I can live without it. 

I had decided to routinely change to LED some time ago and am happy to see that the prices have become so reasonable.

For folks who want to keep using florescent  lighting but want instant on capability and even longer last lighting you can install an "electronic ballast" in the fixture which replaces the original non-electronic ballast and starter.

 

This gives instant-on capability and makes the florescent light last a lot longer also since a high frequency versus line frequency is now being used to power/drive the florescent bulb.    You might want to think of an florescent electronic ballast as the driver circuit (a.k.a., power supply) in a LED light fixture.   Screw-in bulb type  florescent lights use electronic ballast...that why they immediately turn on.

 

10 years ago when I first bought my new house here in Bangkok I immediately began installing electronic ballasts on my florescent lighting fixtures...took me about a year to complete the process....just took my time.  Just couldn't stand the turn on sequence for a standard/non-electronic ballast florescent light...you know, the flicker, flicker and a few seconds later it finally comes on.   Did the lights we use frequently within the first six months or so and got the rest of them over the next six months.  And 10 years ago LED lights were not really an option since there were few LED lights available and the ones that were were expensive.   

 

However, but, if I had just started the swap-out process say "today" I would go with "quality" LED  lights in almost all cases since LED now come in all shapes and sizes, color temperatures, and save a little more power than florescent bulbs,  etc., and probably does last longer that electronic florescent bulbs.    I'm not prepared yet to say LEDs light fixtures last longer "for sure" than florescent fixtures using electronic ballast because I don't have that "long-time personal comparison experience" between the two yet....and don't always believe manufacturers perfect world life ratings.   Plus one of the LED brake lights I used to replace the incandescent brake light in my car burnt out after only a year....and I sure see a lot of defective/partially burnt out LED lights on vehicles running around Thailand....but those LED lights are surely pretty cheap/lower quality. 

 

While LEDs usually come with 30,000 or more hour ratings and florescent bulbs with 10,000 to 15,000 hour ratings that is perfect world, manufacturer ratings.  And while the LED "light itself" (the part that shines bright) would can indeed last a long, long time--longer than a florescent light--unfortunately, the LED must be power powered by its driver circuit (a.k.a., power supply composed of an IC, resistor, diode, capacitor, etc.) that may fail long before the LED light itself would fail.    How long that driver circuit lasts all depends on the quality of manufacturing of that driver/power supply circuit integrated into the LED light/fixture.

 

Anyway, to date I've never had an florescent electronic ballast go bad...some are 10 years old already...and I've only needed to change one florescent circular tube which uses an electronic ballast over those 10 years.  The tube I had to replace had already been burning for almost two years before I got it converted with an electronic ballast.   

 

Almost all of my electronic ballast are Lamptan ballasts....like the T9 ballast shown at this Lamptan webpage.  Easy to install.   I didn't start with Lamptan because I did any advance research...it's just when I started the ballast swap-out process years ago on the day I was in the hardware store looking at the different electronic ballasts that was one of three or four brands they had on the shelves that day.  I liked it the best while standing there that day, bought a couple, and then just continued to buy them as I continued my conversion to electronic ballast over the year.  I have never had a Lamptan electronic ballast go bad....and I probably have a dozen or so installed around the house.   

 

Now I have had one electronic ballast made by GATA develop and intermittent problem and I had to repair that ballast...it was a simple repair.  I took the plastic cover off to look at its electronic board and found two capacitors with cold solder joints...I  re-soldered those two capacitors and the ballast has worked ever since.  Just defective soldering from the factory the day that ballast was made.

 

Yeap, if you want instant-on and longer lasting capability for your florescent fixtures just install an electronic ballast...easy to install...ballast cost will be average around Bt100-150 per quality ballast.   But LEDs should be your first consideration now days if for no other reason to save a little more on the electric bill as they do use a  less power than florescent lightning.  Yea, LED lighting has advanced a lot and become much cheaper over recent years.

I put in all LED lights when I built the place about 4 years ago. Out of the approx. 70 - 80 LEDs we have, 4 have failed in that 4 year period. None of the 5 outdoor LED spotlights have failed.

Any members who had made big changes to LED made any calculations about reductions in electric bill?

 

But the big one - big reductions in electricity usage by air conditioners. Anything new to share, anything new on the horizon?

Fluorescent 32w bulb + 12w ballast = 44w, LED 18w

Saving 26w/hr/LED.

Out of my 6 lights I'm assuming 2 lights running 6  hrs/night, saving 26x12x2 = saving 0.64 units per day at 3.5bht/unit = 2.24 bht/day

 

Total savings = 817 bht/year

The LED lamps (159bht/lamp) will pay for 5 in 1 year.

I've found it's easier to take the whole fitting off the ceiling to work on than stand on a chair with your arms above your head.

About 15 minutes per lamp.

Turn your fusebox off before you play with the lamps!

i dont know how people can live under daylight fluorescents, the first thing i do in a home is remove all the flouro lights unless it something like a dedicated work room
