Re: LED lighting for the workspace
I bought two LED Flat panels from Stricktlylamps on ebay £32 each. GREAT replacement for 6ft flu tubes... I have not detected any QRN fron the panels. All the visitors to my shack/workshop are very complimentary.

Thinking out loud--- For bases, I've often wondered if modified/unmodified starter bases might solve the problem of GU10 holders. Again, commercially available bases are expensive for solving the problem, but a pint or two to a local recycling centre ( AKA tip) operative, in exchange for a few might be a cheap way forward. |

These would be ideal for a workshop, I am sure the creative calibre amongst us on here could come up with a suitable mounting arrangement

Re: LED lighting for the workspace
We have a local supermarket that has what look like LEDs above the ceiling that shine down through frosted sheets that stick down over the check outs and displays.

Re: LED lighting for the workspace
Just to add my vote for Poundland LED bulbs. Available with different shapes and fittings. Far cheaper than anyone else and we have used them throughout the house and shed for some time and so far I have nothing but praise for them.

Re: LED lighting for the workspace
Being a tight wad and to idle to go shopping I buy everything on line, usually via ebay,and sit back and wait for the containers from China to arrive.
A company I have dealt with for a few years on the site for all sorts of LED fittings and lamps is rf-ning whom I have found very fair and reliable. When I had some short life lamps, possibly because they ran too hot in the fittings, this seller sent more without argument, asking me to send the duff ones to a Birmingham address and sending me even more lamps FOC to recover the postage. |

Re: LED lighting for the workspace
After a bit of searching this morning it seems that ES bulbs come in either 2700k, 3000k "warm" or 6000k "cool" but not in 3500-4000k, or even 4500k "daylight/natural" colour temperature. In addition, many were showing out of stock, so it looks like I will have to opt for a LED batten fitting. The cheapest I have found so far is £19 for a 36W 4ft batten from Led Palace, a UK seller on eBay. This is almost the same as 3 x ES R63 bulbs would have cost from a UK outlet. At 36W it should provide a bit more light than 3 x 8W or 9W bulbs would have given me. The light temperature is 4500k so not quite within the 3500k-4000k bracket mentioned earlier but I do have another use for it should it fall short in terms of quality of light. For the price, I figured it was worth a trying one so the order has been placed and I will post an update when it arrives.

Re: LED lighting for the workspace
I doubt if you'll notice the difference between 4000k and 4500k unless you were comparing them side by side. Best of luck anyway

Re: LED lighting for the workspace
While the Poundland LED lamps are great value, the Home Bargains ones seem to be considerably brighter for the same Wattage. They cost a bit more, but are still firmly in the 'economy' sector.

Re: LED lighting for the workspace
i did tout the 3500k to 4000k range as a happy medium, but we all see things in subtly different ways and this was just my opinion..!
As WaveyDipole has noted, there is a gap between warm white and daylight white that the LED's haven't filled yet- maybe they will one day soon. 2700k is a little pinky-yellow for some tastes, and 6000-6500 rather fierce and slightly blueish. My other half rejected a concealed fluorescent tube (daylight sim 5300k) in the lounge as it was, (and i will admit) 'rather harsh and greenish'. We settled on an ancient NOS 4300k Wotan T12 tube. |

It is perhaps also worth mentioning that I did find some confusion in product description with some manufacturers/sellers (especially on eBay) using the description 'daylight white' as a synonym for cool white, a.k.a 5000-6000k, whereas others make the distinction between warm (2700/3000k), daylight/natural (4000-4500k) and cool (5000-6000k). So I found it best to check the actual colour temperature specified rather than rely on the description. Unfortunately I noticed that the occasional listing gave just a descriptive term like 'daylight' or 'natural white' and omitted any mention of the colour temperature so it was difficult to know exactly what one might get.

Re: LED lighting for the workspace
At the risk of sounding like a worn-out 78rpm record ...
I use the self-adhesive LED-on-a-strip: https://www.amazon.co.uk/JnDeeTM-Fle...ords=led+strip Cool white for this product is quoted on the packaging as '10000K'. Warm white (3500K) is also available: https://www.amazon.co.uk/JnDeeTM-Fle...VYJHAARXYTF1X0 The strip can be cut to length at intervals (there are guiding marks so you don't cut off the chip dropper resistor for an LED the other side of the cut ... you only do it once ) I fix the required length onto plastic rectangular conduit which can in turn be fixed to any surface using suitable screws. The lid hides the screw-heads and the conduit provides cable management at the same time. The product is rated at 12v however I've found 11.0 volts reduces the current draw by a significant amount while maintaining a good level of intensity ( e.g. for a 1.5 metre strip: 415mA -> 250mA) I'm thinking of designing an 11.0v, 3.5A regulated (linear) power supply as the 12v Netgear 1.6A adaptor I've been using gets very warm within ten minutes! No connection with this supplier, just a satisfied customer.

Re: LED lighting for the workspace
These photos were taken a week or so ago but they give you an idea of what I've been working towards.
Apologies for the uncommanded rotation of the images ("they were alright leaving me"). Guy |

Re: LED lighting for the workspace
The LED batton arrived today and I have improvised a couple of fittings to install it (unfortunately I can't just screw it into the ceiling). The light temperature is pretty close to daylight and quite neutral, not straying into the harsh blueish tinge of "cool white". The light emitted is a significant improvement over the previous incandescent fitting, both in terms of power consumption (36w vs 180w) and quality of light, which is much more even and brighter. Only time will tell whether it lasts the duration, but overall I am pleased with it anf grateful for everyone's the comments.
