Additional:
For those of you that don't know, most LED's CAN be dimmed.

DC circuits use square wave where as AC uses a sine wave.
We use a Pulse Width Modulator, It's just a matter of turning off and on X amount of times per second, which in turn gives the Dimming effect.

I've installed systems that come as a package which give you control of all circuits in the house via a remote control ash ell as the wall mounted PLC controller switch...

Del loves PLC's he does...
More than worth the extra installation cost against the "oh, sorry Dad, I forgot to turn the light off"

Or if you are a simple person like me you can purchase a LED dimmer at most stores in Thailand that specialize in LED's. They are kind of expensive here so I purchased several on Ebay for 121THB each, from a seller out of HK, who shipped to Thailand for free

Appreciated Shastadad, I full well know about these things and still shudder... Just look at it ! Honestly, It's not exactly 21st century is it mate? Very 70s... I know we're in Thailand but us farang's needn't follow suit In My Opinion.... In MY Opinion - it's not a request or demand for the haters ;)

At 121฿ you certainly get what you pay for aye.

I suppose I should've posted these pictures as a visual understanding to my post, people like pictures...

Image
Obviously the higher end of the market that hotels and rich farang's have installed over here, very popular in Singapore domestic homes too due to the energy saving...

Image
Something more affordable for a Thai lifestyle type of person, Not so aesthetically pleasing as above though, agreed?


Image
This picture shows how simple the PCB is and with the price of touch screens nowadays these systems can be very affordably built.

I'm not saying this is "the best way to do it", I just like to keep up to date as I love all these gadgets and gizmos that make our lives easy.


Now before my nemesis' jump up and down on this, I want to say that I'm NOT saying this is the ONLY way to do it, I agree with you that those cheap 121฿ units will work for a while... But like I said, you get what you pay for...


Thanks for explaining the Star Wars thing Shastadad... I didn't mention that part because I thought it was self explanatory...
An Amish community comes to mind ;)

Del,
Why is it that LED's never seem to give off enough light?
All the ones I have purchased, except for the Italian 2,000+++ baht ones have either stopped working or give off so little light I have binned them.

Maybe a good time to check back with your mum.

The 5 watt Osram I got from either Tesco or Big C was too bright so swapped it back to the 3 watt version and AFAIR it was about ฿300

Perhaps I should swap the few remaining 10 watt ones I have left for 5 watt? I put in a bank of 4 over my stove but the two halogen 5 watt ones in the exhaust fan are brighter. And the bracket of four in the spa bath room are so dim it's a waste of time turning them on when I have three eight watt spirals that light up everything.

All LED's are not equal it very much depends on the LED used

this style is dim.

The LED's with flat emitters are bright to blinding depending on the emitter type and the number of emitters used.

The style that was too bright was shaped like a traditional light bulb

That was why I asked the original question: Why do LED's never seem to give off enough light? For the 300+ baht you spend on them and what they claim they will do, it never seems to happen with me. The exception being the Carini LED 10 Watt I bought for 2-3,000 baht.
I have over 100 spiral lights in this house ranging from 8 to 11 watt, none of them have stopped working, all give off excellent light no matter the brand and they cost peanuts. I just want to know why that is so.

I can't answer that question without being there to carry out tests...

RR, certainly agree with you. LEDs never seem to give off the light claimed on the packaging, not only that but according to researchers at the University of California say when you raise the current up to the level it takes to light a room, nitride-based LEDs stop producing photons at the same rate as low power units, like in your cell phone, According to the research from UCSB's Centre for Energy Efficient Materials, it's because the electrons collide with each other and lose their energy through heat instead of light.
It's not who you know, it's whom you know.
