Daylight lamps 24w 6500K (may assist SAD) in bayonet and ES fit @ CPC Farnell £2.47 (for 5+) delivered, 1-4 lamps are £2.82ea, 20w from £1.61 (Minimum order for free delivery £6)

Even cheaper than last time (4 months ago) for all but the 24w, these low energy lamps, available in 15w, 18w, 20w and 24w versions with warm, cool and daylight option too.
24 watt daylight energy saving lamps (roughly 100 watt incandescent equivalent) in bayonet(B22) and Edison screw (E27) fit. These are 8000 hour rated (typical 'old fashioned bulbs' are 1000-2000 hours) and 6500K - Kelvin, meaning very similar to daylight.
I have been changing to daylight as I much prefer the clean crisp light they give. Walking into a room lit by these can mean it is difficult to realise there is a light on as they are so similar to natural daylight. The problem I now have is rooms with warm white light look dirty (they are clean!) and poorly lit.
I keep hearing people saying these make your home look like a hospital or dental surgery! I strongly urge you to try them for yourself. My home looks like a daylight lit home with these on, if you live in a hospital or dental surgery then these lights won't change that.
24w=£2.35+vat, £2.06+vat for 5 or more,
All others are £1.45+vat, £1.34+vat for 5 or more.

Heat for dark, cold days.

What is daylight? Is it CFL?

Wow! Excellent post in my opinion. Went to Homebase last week and paid £7 just for one daylight bulb for my kitchen. Tried the blue bulbs from Maplins for £4 but not as strong so put that in my downstairs loo. Agree, the light is a massive improvement to the dull, yellow lights from ordinary bulbs. Brilliant for putting makeup on in the dark mornings too, just like daylight. Now have one in the bathroom ands looking to replace all bulbs. Heat from me.

Any chance of getting SBC

Use 'normal' bulbs in lamps during the evenings (7pm onwards) to prevent this.

Not from CPC, B15 (SBC) has limited options(most of the world uses screw in lamps). There is the option of a converter if you are desperate.
Whilst bayonet is a UK 'standard', I try to avoid using fittings with bayonet lampholders.

For those that are unaware, it might be worth pointing out that there is little supporting (peer reviewed) evidence that light therapy for SAD has more long-term benefit than placebo.

Of course there are many sources that say otherwise, but coincidentally they often seem to be the same organisations that want to sell you expensive lightbulbs (or receive donations).

I won't argue with your comment regarding lacking SAD evidence. I can tell you I feel better having the house lit with daylight. I make nothing from the sale of these lamps (except happy HUKDers).

Yes sorry, I wasn't suggesting that you were up to anything untoward! I'm glad it makes you feel better (which is the important thing).

Personally speaking, I get a benefit from "sunrise simulation". You don't need one of those silly special alarm clocks either, a cheap plug socket timer and a bedside lamp, set to turn on a couple of hours before you're due to wake works as well. If you haven't tried it I highly recommend giving it a shot.

So you have to change bulbs every evening? How inconvenient.

Not as fan of CFL bulbs due to their mercury content.......I will always seek out LED alternatives which may cost more but last longer & don't have the same negative environmental impact

If you do like CFL bulbs though these are a good price

Oh yes, 'peer review' - hardly a stamp of authority in any field these days, let alone public health. You'll find conflicting evidence in pretty much any area - take nutrition - salt? jury's out - saturated fat? no different from any other kind - sugar? flavour of the month - even five-a-day? certainly no evidence of any benefit there whatsoever - as for SAD, well of *course* its all in the mind - that's where depression happens - it's very difficult to get objective measurement of how somebody *feels* - but for those of us who suffer from living at latitudes which are uninhabited/uninhabitable for most of the land surface of the Earth - take Labrador to Alaska, for example, any assistance is very welcome. I bought two a month ago and hope they work as well as my light box this winter.

Looks like a steal but I've never really been much of a fan of CFL bulbs. Not only can they be dangerous due to their mercury content (as mentioned above) but they also emit UV radiation which can damage eyesight and be harmful to skin cells (apparently). Another thing I don't like about them is their unnatural colour and lack of a sharp shadow compared to the likes of a halogen bulb.

huffingtonpost.com/201…tml
energyblog.nationalgeographic.com/201…ed/


That being said halogen bulbs are my favorite and I don't think there will be an overall better alternative any time soon. I like some of the LED bulbs that are around and they're great for the kitchen (as long as they're bright enough) but I wouldn't really want them in my room or living area. I don't like yellow bulbs and I'm no fan of white hospital like lightning either.

Ignore all the so called science on here from armchair experts

Its a bright white light which is better than that horrible looking yellow light that makes your house look dirty. Got these in all rooms except one & I would never go back to to yellow lights again!

R u sure these are for SAD it says nothing about it on the product page?

Buying a SAD Light

"Are Full Spectrum and Daylight Bulbs SAD Lights?

No, not at this time. Unfortunately due to clever marketing many people believe they can get a SAD Light treatment just by buying a full spectrum bulb or daylight bulb but this is factually incorrect.

This is misleading as unless the bulb emits 10000 lux they cannot be classed as powerful enough to treat Seasonal Affective Disorder. At this time there is no standard bulb, full spectrum bulb or daylight bulb that is powerful enough to treat SAD. The bulbs emit a pleasant light that can reduce tiredness and give better visual accurity but their benefit in treating SAD is unproven and not based on any medical evidence of which SAD.org.uk are aware.

These lamps are not marketed as assisting SAD sufferers though there are people here and elsewhere reporting benefits. If you don't wish to invest a few pounds to test the idea that's your choice. I'm happy to have these lamps in my home, as are my family. I can walk past rooms in my home and not realise there is an artificial light switched on.

looks like an ice cream

bought a couple to try.

The problem with halogen and possibly LED bulbs is that the light is very concentrated in a small area and that can mess up your sleep patterns if the bulb gets in your line of sight. I know this because i had that problem from a halogen bulb that wasn't even that powerful.

Wow what silly bickering !!

SAD lamps - whether there is efficacy or not - are very high lumen output. Nothing like these.

Can I just say though - the peer review process is the gold standard in scientific enquiry. It is typically those who misinterpret the reports who do the damage. Tabloids, journalists, bloggers. That is why you get so many conflicting reports on such things. Results are grasped by people with biases and overreaching claims made - a practice which has nothing to do with the scientific method. It's worth reading the source material on controversial topics, eg dietary advice. This takes time, but once you've assimilated a few, you get a grasp how to pick out the reliable information and discard tittle tattle. And remember folks, correlation is NOT causality!

Anyway, it's absolutely true that light in the blue end of the spectrum late in the day has a detrimental effect on sleep. If you want quality sleep, you will notch down the blue end some hours before sleep.

This is the basis for the extremely popular program f.lux. It has been a lifechanger for some and it's worth a try even if you think you sleep well. The effects can be profound!

I'm ordering some of these daylight bulbs for a study and kitchen - daylight bulbs are very pleasing light, and much better for anything where natural colour reproduction is appreciated eg photography and art. But as the evening progresses I veer toward warm lighting.

That's not true. By calling them SAD lamps that's exactly how you are marketing them.

Once tried you won't go back - It's like going from candle light to the electric bulb.
its such a natural light, It does take short while to adjust on the 1st night because it's like wow everything is so clear and fresh.
If I go into a house with yellow old style bulbs it's like stepping into a different era - is very surreal. I would never use yellow bulbs again
I usually pay around £6 pound each so lot of heat.

That is something I cannot comment on because I've always enjoyed staying up late and my sleeping patterns have been messed up ever since I can remember. I reckon the reason for this is due to being more of a night owl than a halogen bulb being the culprit but then again it makes me wonder. I don't sleep with the lights on, so?

On the other hand, after reading some of these comments I'm feeling like I may be missing out so I think I'll go give these a try.

Peer review and evidence for the things you say are generally pretty solid. The problem is how it's reported and presented in the media. You'll get 100 studies saying the same thing, then one comes along contrary, and it makes headlines, and make out like it disproves the other 100. Salt, sugar, and saturated fat have reached a consensus, with solid evidence, but there will always be some outliers that disagree, because we don't know all the factors at work and can't eliminate all variables.

SAD lights are high lux at very close proximity (25cm roughly), some of these lights use as little as two 24w cfl lamps, so quite like these?

These are great for hobby work.

Their website sucks. Don't like how they process your debit / credit card information. They've stored those details where I did not want them to store them.

Order was apparently successful last night, today I received an email stating that authorisation for payment did not succeed. I did not provide a landline as I don't use one, so instead I provided a mobile number and apparently that could have been the issue.

Will be calling them later to get my details removed. Never had any issues with buying online before, so it must be them.
