Kitchen lighting

Has anyone any experience of these (for kitchen lighting)

go in fitting

2-3 sec for any light, 30 - 45 sec for nearly full brightness Performance is easy to live with

Agree. Just to say the quoted filament equivalence is a complete fabrication. Assume about 1:2 ratio for such small CFL reflector lamps, i.e. equivalent to about 22W filament lamp in this case.

Also, I can't see what type of recessed can in the picture. If it's sealed, then you probably won't get enything like the rated life from the lamps as they'll run hot. If it's vented with an intumescent closure (much less common), then the lamp life will be longer.

To go in fitting --

GU10 fittings are rubbish, no ifs ,buts or mebbes , GU10 is a useless lamps style with terrible beam control , awful efficiency and excreable lamp life.

GU10 CFLs are a half baked answer to a problem that should not have existed.

A GU 10 fitting that is designed to take a GU 10 CFL is some marketing guys weird Frankenstein creation of a useless idea.

CFL works very badly in a 50mm aperture, all the light illuminates the space inside, look at the lamp , its the bends of folded tubes acing out, meand the straights are happily lighting your ceiling void.

Closed back fittings and CFL electronocs usally dont play well either,

15K hours is a pipedream.

Megaman make some decent CFL stuff this most certainly aint decent.

Get some good quality T5 fluro fixtures, if you have ceiling void get some nice flush mounting ones or cheap out and use some Cat2 office ceiling louvres fluros.

If you want spots use LV halogen.

Kitchens are dangerous places , plenty of light is required not very questionable energy savings.

If you want to save power, put the computers into standby and walk to the shops.

Whatever don`t fall into trap of thinking there is anything `green` about these hokey CFL GU10s.

Lidl are doing some under cupboard ones this week.

[Andrew Gabriel]

These are often T4 (doesn't say). Beware that T4 tubes are not standardised, so you'll only be able to fit the manufacturer's tubes. This means you have to buy from somewhere which sells spare tubes, and expects to do so for as long as you intend to keep the fittings. That doesn't really describe Lidl IME.

If they're T5, these are standardised, although tubes other than the old 4/6/8/13W ones haven't made it into retail outlets (although they are heavily used in commercial premises).

[Richard Russell]

Indeed, but matching colour temperature can be a problem. I bought five T5 tubes from TLC *at the same time*: four were a cold white and one a warm white! All TLC could suggest was to return the lot (with no guarantee that replacements would be any better matched) so I'm putting up with it. Their online catalogue lists 8 different phosphor types, but unhelpfully doesn't say which they supply (seems to be pot luck).

supermarkets. Could be good as under cupboard lights. Any views?

Also - I wish I could buy an attractive modern fitting for a circular fluorescent - not one that looks like something from the 1960's.

RS components do them at reasonable prices (surprisingly much better than TLC). 300mm ones only in warm white but longer ones in different temps.

[Adam Aglionby]

Its a slam dunk for LEDs, get more efficient as get colder and run cool themsleves, they are the ideal fridge light.

Fluro tubes which they replace in application get less efficient in low ambient , harder to start and dosent help lamplife.

No where near as bright as T4/5 , even in high density, as main worksurface light, without spending serious money, no.

As kickplate and cupboardlights pretty much unbeatable.

Many thanks. We already have a

but there is one area of frequently used work surface that could do with additional light in the evening. It appears that one or two LV halogen may be the answer.
