LED kitchen lights / battens

I've only changed 4' fluo tubes for LEDs. Ecellent results.

Cheers! What about the relative brightness? Which LED make did you choose?

FWIW I recently, in our kitchen, replaced a Ceiling fitting with (IIRC) 2off 5ft Fluorescent tubes (T8? sorry, can't remember), with an LED *Panel* light - one of these:

I paid (to my eyes) for more than a basic one; This has remote setting of brightness and colour temperature.

I've actually been really pleased with it. The ability to set both brightness and colour temperature is nice, and the lack of an inrush 'hum' on startup is also pleasing. Like you I was a bit concerned about the possible difference in output lumens (sorry, haven't got my figures to hand), but the effectiveness of the lighting has been at least as good.

My main reservations are the initial cost, and the non-replaceability of the panel, but in this case I decided it was worth it.

If the tubes are old, their light output will be down. My experience is they compare well. The eye sees light in logarithmic terms so if there is a 50% reduction in Lumens, it won't be seen as perceived 50% drop.

Thanks Jon, that's a bit out of my league though.

This might be in your league:

I recently changed a 4' 36W tube for:

that's about right. Tubes vary a fair bit in output.

I wouldn't buy those, they're just over 100lpw, and 200lpw LEDs are already on sale, and will be cheap soon. Better to use something that takes BC bulbs.

I had no light meter, I just used my eyes. Make? Whatever TLC supplied me with.

I have a single Thorne 40w tube in the kitchen, and do not want to do much decoration. The tubes are the thicker kind with the bi pin either end, and am seriously considering LAED replacement of the tube, which seems to consist of a dummy starter and the led tube. I myself don't need light, but my PA and friends say the tube is well past its best now and is probably a waste of current, and the fitting buzzes. Would I be right in simply doing the swap? I'm assuming these lamps also come in a different range of whites do they?The original tube says warm white on it apparently. Brian

I've bought these from CPC and am very happy with them:-

Instead of going for battens again, I suggest a couple of circular LCDs.

These ones are very unobtrusive, only 18w, and they give a very good light.

Yes, I also fitted something like that elsewhere, when I was also doing the kitchen light. also happy with how it's turned out.

Brian, replacing the tube would be the best bet, unless you have someone that can replace the whole fitting for something that looks nicer.

An old fat tube labelled warm white is likely to be halophosphate. These are less efficient & deteriorate faster than the later triphosphors. And warm white was one of the poorer performing tubes to begin with.

Hard to guess what wattage you'd need, anything LED should be a real improvement. Current will still go through the ballast, but less, so less likelihood of buzz.

I've done this with several T8 pin tubes. Not seen a version for the older wide pin fitting.

T8 & T12 have the same pins

Then get an app on your phone.

They are surprisingly accurate when compared to proper calibrated lux meters.

The same applies to dB meters.

Why should I bother?

I have that app.

Indeed. I was simply warning that very old fittings may not suit LED replacements. I have a barn with about 20 twins fitted:-(
