RIP (The old fashioned light bulb)

[Dustydazzler]

Halogen light bulbs banned from all shops from today - saving homes £200 a year

so the heat generated by my old haolgen bulbs that added some warmth to the room will now need to be replaced with an alternative energy source. more gas used by the boiler or an electric heater in the room?

 

[Mikegh]

Well overdue

The quicker they're done away with in downlights the better.

 

[Dustydazzler]

My parents still have the old R80 downlights in their house , good job they purchased 4 boxes of R80 bulbs from the local wholesalers the other month. 16 pence a bulb

I suppose my stash of about 50 halogen GU10s is now worth considerably more than before...

Are they being taken off the shelfs?

I got LED replacements, though maybe not quite full size (R63?) that do a good enough job.

What none of the LEDs do well is dimming.

Or rather, LEDs dim just fine but the cheap built-in driver circuits don't. At least, not 230V ones using phase-angle control, which is not surprising as it is fundamentally the wrong technology for the job. What we actually need is a re-structure of lighting circuits to run at say 24 or 48V DC, with HF PWM dimmers as standard instead of 50Hz.

No more heating the lunchtime pies on an upturned 1000W floodlight

 

[littlespark]

But also, no more burning fingers on replacing a lamp if you didn’t turn the power off!

I was still an apprentice!

Up a ladder, had the tube in a bit of paper as instructed. Slotted it in, and the bit of paper burst into flames

That is like the joke about asking the village idiot for instructions and, after some thinking, he says "Well, if I were you, I wouldn't be starting from here".

We have 230V lights and phase-angle dimmers, but nobody seems to have put much effort in to making the LED driver circuit react well to them. Better systems do exist, but I suspect it will be very long before many houses have anything new.

Want to add several thousand 30W MR16s to that stash?

Where did u get all them

 

[nicebutdim]

Where did u get all them

Leftovers from a sizeable clearance a few years back. They still sell well enough, but MR16s were never going to move as quickly as more common lamps.

 

[Mikegh]

There'll be demand for them still

Some will upgrade and others will be resistant to change as usual

I'll stick to my 1920s carbon filament lamps thank you. Rated 16 candle power!

 

[Mikegh]

I've an older pir switching a 15w incandescent in top hall -thats staying cos it flickered when I tried an led

No problems with led/pirs elsewhere in the house

I've only got the one gas light, the rest are paraffin.

There is more demand now than ever I'd say. Plenty of jobs in shops I go to require them and they are getting hard to find.
