Light Bulb

How long does it take to get a light bulb from Amazon ?

So why would it take so long ?

Re: Light Bulb

I suppose it is out of stock?
If you have a local ToolStation they have had good deals on Philips LEDs.  Also Robert Dyas (Osram LEDs).

Re: Light Bulb

1-2 months, I guess they make each bulb to order from scratch, making the LED chips, the capacitors, the resistors, everything inside the lamp all from the ground up... Grin

Not as obvious as it looks.  Old energy efficient bulbs take a time to warm up to full light.  An our new LED friendly dimmer switch likes to be kind to the LED, which includes a warmup so no light at all for 2 secs after switching on.  (So visitors get confused and turn it off again before it comes on)

Re: Light Bulb

Surely it isn`t worth spending £8 on a bulb, to alleviate the 2 second delay....  Roll eyes

I have a few LED bulbs that will last a great deal longer than that Smiley.......because they have been replaced by newer ones which do a much better job at half the price Angry

Surely it isn`t worth spending £8 on a bulb, to alleviate the 2 second delay...  The two second delay comes as a result of paying whatever (I think it was just under £8 each) for the bulbs and somewhere around £15 for the dimmer.  Still probably worth it.
We're just guinea pigs except that guinea pigs don't have to pay to take part in experiments!

Bit longer than 2 seconds for an aging energy efficient bulb though isn't it shutter. As they get older they can take over a minunte to brighten up fully..
I need a new signature... i'm bored of the old one!

Whilst these bulbs are cheaper than the ones in my original post there is not much saving when you add p&p to the price.
Philips are a well known make but I have not come across this other make before but accept the only thing that counts is how go or how long the product lasts

Re: Light Bulb

@7up.... well, I have those "old fashioned" energy saving bulbs... and I can`t say I have noticed any 2 second delay in them giving light on switching on... they light up immediately, the may take a couple of seconds to give out "normal" light power...but that is no inconvenience....
so the "claim" that they give " Instant light when switched on " is no different to any other bulb... they all do...  Smiley

Re: Light Bulb

I can tell the difference between LED bulbs and CFL Energy Saving bulbs as far as start-up is concerned.
I currently have both in various rooms and my CFL Energy Saving bulbs take about 1/2 a minute to reach full brightness. The older they get the longer it takes.
The LED bulbs reach full brightness instantly.
My daughter doesn't like the CFL bulbs because of this 'feature'.

Re: Light Bulb

I'm still a CFL user (bought a 6-pack of 4100k Philips Tornado CFLs recently for £15, so about £2.50 a pop), White LED technology to me hasn't developed enough for my liking, not to mention, the price isn't to my liking either, plus you get all kinds of LED bulbs now, and a lot of them, even known-brand ones, which are really poorly made to the point where they are actually dangerous, yet are legally sold this country... Shocked
Couple of vids on exampled of "legal" LED lights:

If you do buy those LEDs, make sure to turn off the power to the whole house, just incase... Shocked
