ASDA 100 watt daylight bulbs

sweetgirl2015

Was wondering if anyone had the same problem as me obtaining ASDA's own brand of 100watt daylight led bulbs?
I contacted my local branch and they said they been discontinued, but I fail to see why as they are a brilliant bulb all be it a little over priced at £12 for a pack of 2 bayonet bulbs, but very energy officiant.
The problem is I started buying a pack each week to gradually do the whole house, but after I bought 3 packs they were gone from the shelf. 
Any ideas? I have left a link below to ASDA official web site so I can include a pic of them.

cheap doesn't always mean good

Concentrate the ones you bought maybe upstairs and start again with a more reliable brand.
Those appear to be an old style that's probably ended it's production run.

100W bayonet don't seem to be very popular for some reason (we have them in living room because we like the brightness for reading.)   BUT would find daylight very blue.  Here are some well reviewed at Amazon but note the transparent area is much less than traditional globe bulb...

I have some and they do run rather warm. Maybe the lifespan is too short.  You say they are efficient but

in reality they are fairly average.

Not a fan of how they put 100W in really large fonts and then hide away the real wattage which is

11w or 12w depending on the colour.

yeah I don't know why people are still buying them based on the power they consume. wouldn't it make far more sense to buy them based on how much light they produce?
look for lumens

Sort of on topic! I heard a couple of years ago that graphene light bulbs were the next ultra low energy thing, but seems to have gone quiet. Anyone know if they will be rolled out soon  ?

I don't think i've ever heard of them marketed as ultra low energy, I think technology has got the power consumption down to as low as it needs to be for now, they just need to focus on making them last longer.
they make graphene bulbs now, they are the ones that look like old fashioned filament lamps. they aren't as efficient, don't last as long (yet) as a bog standard white frosted LED though and cost considerably more (as they look a lot nicer)

It is a lot more sensible to buy light bulbs based on the amount of light they produce.  Back in the day when all there were only incandescent bulbs wattage was a good proxy and fittings with wattage limits were based on the heat output it made sense.  Now with all the different types of low energy bulbs using different amount of power to produce a certain amount of light the lumen rating is the way to go.

I think the point with Watts is that there were only about 4 wattages in common household use, you didn't really have to worry about colour temperature and you can envisage how bright they are from the use such as a 60W table lamp.

Lumens now seen to be one of many variables and are often expressed as odd figures such as 357 or 452 lumens. Whilst one is clearly brighter than the other, I have to divide it by 10 to get a ballpark figure of how bright it is, in this case, about the same as a 40W bulb which I can envisage.

Presumably it will start to change with the younger generation as did inches to cm and Fahrenheit to centigrade.
