Halogen to be banned

Yeahbut, turn a 60W incandescent lamp on for 10 seconds and then try and touch it. Have a 60W (light equiv) LED lamp on for 10 minutes and it will still only feel warm?

Suggesting, that (light) like for like, LED's are generally much more efficient as they generally run much cooler?

(I've got a 15W (equiv) desk lamp on here set up to the Home Automation to come on when the light level drops below a certain threshold and it's been on for a couple of hours now. Whilst it's 'warm' I can still easily unscrew it and take it out, not something I'd try with even a 15W incandescent that had been on for a fraction of that time). ;-(

What, even the stuff coming out as visible light / UV light?

I tried some 6,500K panels in the kitchen and I had to send them back. They were soooo cold!

Do you mean to claim that LED headlights are at present illegal?

Shame no-one told VAG a few years ago when they made my car.

Yeah, the two I did for the kitchen were 'old skool' and I removed the ballast and cap completely on one and just wired it though the non-starter (because mine had 250mA fuses in them) and the other still has the ballast and cap in circuit (for now).

Remembering this particular unit was HF got me thinking that I should have replaced the entire fitting for an LED one, however I think I'm better off saying with the 'tube' design as then I can swap out the tubes if they fail or if I want to change the usage (less bright, warmer etc) without replacing the entire unit.

I'm probably also going to include that lamp into the HA with an occupancy sensor as I'm generally only turning it on when working in there or setting up the 3D printer. I'm getting too used to the hall, kitchen and landing lights going on and off automatically (movement / occupancy) it seems quite 'primitive to have to still turn some on and off yourself. ;-)

Mine has (factory) LEDs, newer models have laser headlights, but I think that's just using a blue laser diode to illuminate a phosphor to produce the white light ... not able to blind cyclists :-P

Agreed, however, the 'hum' clearly goes on and off with the light so if it's not from the fitting it's from the tube itself? Unfortunately I can't easily test the LED tube in there because it's an HF fitting. ;-(

But then I did have similar with one of the 6' fittings in the kitchen that was the LED tube (I just thought I hadn't noticed it with the florry). Took all the guts out completely, that fitting with the second hand LED tube in it still hummed like a goodun? ;-(

Two new LED tubes from TLC seemed to cure it. ;-)

(I may be hypersensitive to 50hz because of my tinnitus).

+1, although I have several of the little desk lamps with "radio aeriel" power feeds that use G4s. However I can report that I've just put a LED replacement in one that has just failed and although it is perhaps not quite so bright, the output is acceptable.

Volkswagen is a criminal company :-)

Effectively, they are. However, supplied as part of a homologated car, they have to be accepted under EU rules (and we are still sticking with those) and the DOT has gone so far as to say that it would be unreasonable to not permit retrofitting to cars that came without them - however, there are requirements that make retrofitting possibly expensive and difficult (wash/wipe and self-levelling).

Just another reg thought up by either civil servants with zero technical knowledge or pressure groups with self interests.

In theory fitting replacement headlamp bulbs is now an MOT fail. Although not sure how the tester is going to know they are fitted, since he's not allowed to dismantle anything. Poor beam control causing dazzle is already covered in an MOT - although I often wonder how some factory fits pass this.

This may or may not help.

Halogen is regarded as 3000k, or warm white.

If you want to stay awake, the the cooler temperatures, to go to sleep then perhaps aim for the warmer temps.

Most LED tube replacements specifically say they should not be fitted without the HF ballast first being removed.

Generally they're twice as efficient as fluorescent tubes. As this link demonstrates:

The ballast also generally consumes a few watts.

Huh! Put up with an access tower on bare floor. Place is half full of fixed machinery now.

Might be doable with an agile bloke from Doncaster:-)

I have 6 x 12 V MR16 bulbs in my bathroom, fed via a Dimpull. So far they haven't made a version of the Dimpull that can handle LEDs.

In the 16 years since they were installed (tempting providence) I don't think I have changed any bulbs, of which I have a stock, but I am on my 3rd Dimpull. Its soft start is obviously good for bulb life, just a shame its own design isn't better.

Extrapolating, I don't think I need to worry.

No it is illegal to convert the factory fitted halogen headlights to LED

Yes. But 2700K is the old incandescent colour.

Yes, of course, what else do you think happens to the energy?

Some of the light may go out of your windows and the resultant heat is lost from your house but the light will be absorbed by the atmosphere and disappated as heat there.

Ultimately a few photons worth of energy possibly escape into outer space I suppose.

My motorbike has an LED headlight. I think it's *converting* to LED that's not allowed.

Of course not. That becomes pixie dust.
