I have just replaced over 50 18 w X 4 fluorescent light fittings in the office. This was about 6 months ago. The old fittings were 72 w X 50 = over 3.5 kw / hr run time. The new fittings, IIRC are 24 W each. So, we are saving 2/3 of the energy for office lighting. Maths arent my strong point at nearly 11 pm . Over a 10 hr run time day, over a period of a week to a year, thats quite a substantial saving. I was worried with certain staff members being very moany about change and with the old fittings loosing their colour, the change is very different. Much brighter and certain LED fittings can give a grey shade colour. These have none of this and my worries were unfounded as the moaners have taken to them well. The only failure we have had is because of a roof leak filling the fitting and currently the office brightness seems to prevent less straining on the eyes when working. Yes, we had to buy them and although from one of our suppliers , I suspect payback would be reasonably quick, potentially within the year. I have also just changed 3 bay lights in the warehouse , which were 750 watts each. Were a ballache , as they took 4 to 5 mins to ignite and light , which although we had changed bulbs a few months earlier, we guess the lights were tired. We now have 2 off 100 w bays to replace them , so a saving of nearly 2 KW per hour. We have a crisper light and also when our delivery driver opens the roller door to get his van out at 5 am, he can turn the light on and get immediate light, than fumbling around getting into his van to go to work. So, in certain instances, LED modern lights can work and well. As to mine. I wanted a fitting to replace the 300 watt halogen and also hoping to not worry about bulb failures as they always go wrong when its raining or minus 10. As to why it randomly is a pain by pulsing , it has gone back to working fine again. It will probably work now for a few weeks before it goes into flicker pulse mode again. Its a nuisance and frustrating to resolve. I wish I surface mounted the cable now rather than hide it under the roof beam floor and plaster boarded ceiling !! Oh and the other reason for energy saving in the office lighting, was to allow more amperage load free in the fuse board as just fitted 2 off hybrid car charging posts in the car park for company cars to use . Glad also I didnt buy Phillips , who allegedly are the best LED lights , but mine are Osram, a name I have always used and trusted. It still might not be the fitting !

Man On The Clapham Omnibus Posted October 31, 2018 Share Posted October 31, 2018 This was made a while ago after I changed the 6 off 120W PAR38 lamps for 12W LEDs in the kitchen of my (then) newly acquired house. I complained to the supplier and he singularly failed to rectify the problem, but as it is a widely experienced phenomenon I just live with it - for now. It is not the LEDs but the 12Vdc switch-mode power supplies made in a back street in China as far as I can tell. Sound required Quote Link to comment Share on other sites More sharing options...
Blatman Posted October 31, 2018 Share Posted October 31, 2018 How old is your radio? Do you have one of them new fangled digital radios? Does it affect that in the same way? Quote Link to comment Share on other sites More sharing options...
Man On The Clapham Omnibus Posted November 1, 2018 Share Posted November 1, 2018 Wot-Ho Blatters! No, it doesn't affect DAB at all. The tuner is ancient but that model of ReVox tuner was the benchmark against which all other FM tuners were judged by (I think) HiFi Magazine once upon a time. I bought it second hand about twenty five years ago and still haven't seen fit to replace it any more than I've replaced my ReVox open reel tape machine, nor my ReVox linear turntable. I was flush in those days and only good stuff was acceptable. Now I'm half Mutt'n'Jeff and not so flush so that's why I've still got them! Mean? Moi? Mais oui!

Dave Eastwood (Gadgetman) - Club Chairman Posted November 1, 2018 Share Posted November 1, 2018 The audio side will always be contentious, but once upon a time, the dream team for many an audiophile was the Revox B77 reel to reel, Naim NAT 01 tuner and Linn Sondek LP12 turntable. I never did reel to reel, much to my disappointment. But still have some recordings made of the live sessions and gigs the BBC used to broadcast, made from a Linn Kremlin tuner on a Nakamichi CR7; back in those days, at least, no one engineered and transmitted live performances better than the Beeb, in their evening/night time broadcast slots, when there was no compression of the signal. trouble is, haven't had anything to play them on for twenty plus years!

Man On The Clapham Omnibus Posted November 1, 2018 Share Posted November 1, 2018 My reel-to-reel is an A77 four track. What I like about that model vs the B77 is whilst the performance is identical, the A77 is all relay logic but the B77 is solid state and when you need to repair one or the other, the relay logic is so much easier. Parts are now hard to find and are even more expensive than they were when Studer were supplying them through FWO Bauch. My tuner has lost its stereo decoder but as FM is likely to be shut down in the near future I haven't bothered to fix it. I have a handy little Revo DAB separate which does the job nicely. HiFi now seems less important than good music. To paraphrase Marshall McLuhan, the message is more important than the medium nowadays. I'm still using AR18 speakers from the 1980s and a Technics amplifier... Quote Link to comment Share on other sites More sharing options...
Blatman Posted November 1, 2018 Share Posted November 1, 2018 Not an audiophile or anything but I do appreciate the views of those who are. Just haven't seen an analogue signal meter for ages, not since I got rid of my Cobra AM/FM (and highly illegal) CB radio... with burner...

I still have a couple of CBs in a cupboard in my workshop. They're modified to provide an alternative set of channels IIRC but no idea what any more. We had a Thunder Pole on my old house in Beaconsfield and I could contact my Good Lady from Hillingdon at the top of the hill running down to Denham J1 of M40 to warn her to get the milkman out of bed and put the kettle on! I cannot remember when I last switched a set on - no aerial any more. (sorry twig) Quote Link to comment Share on other sites More sharing options...
Blatman Posted November 2, 2018 Share Posted November 2, 2018 Had a Sigma 4 on my parents house. They went shopping and I went up on the roof... The rig was on a slide mount under my wardrobe/dresser unit so I could remove it and put it in the car. Both car and house had 25 watt burners. Car had a mag mount antenna, the name of which escapes me but it wasn't a whip, it was hollow steel tube with a wide base mag mount and conical shaped mount/coil which I presume continued up the hollow tube. Car was a 2 door Mk1 Escort, I had all my hair and teeth and my girlfriend was 16...just... Those were the days Quote Link to comment Share on other sites More sharing options...
Thrustyjust Posted November 28, 2018 Author Share Posted November 28, 2018 Well back on topic The light didn't flash for 2 to 3 weeks after this thread started again. But is randomly going off into flash mode again recently. So my electrical supplier is flogging me a replacement 'better quality' PIR to see if that resolves it. If not, I am swopping the light. If it is the light, I will send it back under warranty and potentially make a portable garage light from it for car working on etc. Quote Link to comment Share on other sites More sharing options...
SootySport Posted February 28, 2019 Share Posted February 28, 2019 Did you ever resolve your light problem? I found a capacitor in Screwfix that cures random switching on problems on PIR lights. Have a look athttps://www.screwfix.com/p/elkay-4uf-power-factor-correction-capacitor/1373g Quote Link to comment Share on other sites More sharing options...

They sent me a replacement and 'although' has been known to pulse once or twice on occasions is definitely not like the acid house party I had before. I even bought another Osram LEDvance 20w for the other end of the front of house and used the sensor I believed may have been faulty and that and the light have been 100% perfect. Must be something odd with the 50w versions as the 20's , which I now have 3 are all spot on. Quote Link to comment Share on other sites More sharing options...
SootySport Posted March 1, 2019 Share Posted March 1, 2019 Hopefully they have now built in the correct capacitor for the new version, hence they are working ok. Quote Link to comment Share on other sites More sharing options...
