Re: Lightbulb help.

Photo? There are some out there for commercial use that have the oversized ES thread, but they start around 45 from what I've seen. But you can buy adapters that can drop them to ES27 so you can use more modern (and much cheaper) bulbs.

Re: Lightbulb help.

So confused about light bulbs now, the last time i bought any they were energy saving twisty looking ones similar to the picture.

What is the equivalent to these now that i need to buy?

Re: Lightbulb help.

Those are CFL (Compact flourescent) nasty things with Mercury in and usually slow to get going. I've also had two go off with a bang. You can still get them and they're better than they used to be.

Modern lamps are LED*, quick to start and often dimmable. Fully solid state. Long life. They contain no nasty stuff and available in a variety of styles.

*Light emitting diode. A specially manufactured crystal that emits strong blue light in this case. Covered with a phosphor that converts some of the blue to yellow, by varying the mix you get the different qualities (Colour temperature) of white.

Found this on Amazon but it's 400W. Since it's not an incandescent bulb, would that matter?

Re: Lightbulb help.

I'm looking at gradually replacing all my bulb as they die with Philips Hue bulbs.

The downside is cost. Upto 50 a bulb.

But hall lights will be pure white and around 13, and some I might do white accents which are 25.

I know many who use those lamps for raising chilli plants, and are shocked when they see it's size and weight.

I was gifted an LED array called a UFO that kicks out 9250 lumens. You daren't look anywhere near it....

Due to the EU rules, I'm having a hard time sourcing a replacement 300W dim-able incandescent and the LEDs that I've found aren't dim-able or 300W.
Can anyone point me in the right direction?
Is this it https://www.ebay.co.uk/itm/CROMPTON-...MAAOSw3aNanr8Z

Dimmable LED are designed to work with LED compatible dimmers, it's uncertain if they would provide sufficient hold current for a conventional dimmer unless sharing with a conventional bulb, and the response range could be narrow.

Re: Lightbulb help.

One thing that you have to do these days - pay attention to the colour temp of the bulbs you buy!

At Christmas I decided it was time for my Dad to get swapped from CFL bulbs to LEDs - the CFLs were taking ages to start up so didn't actually help when you needed light.

However I ended ordering the wrong colour temp bulbs from B&Q - ended up with Cool White rather than Warm White bulbs.

Didn't notice until I started swapping them and wondered why the rooms looked odd.

Luckily B&Q are pretty good for their returns policy and manage to swap all that I needed for Warm White bulbs. Actually ended up leaving a couple as Cool White as they seem to be better for reading and working.

Re: Lightbulb help.

There is also a "Daylight white" lamp available now.

Midway between warm & cool.

Have a look on SCREWFIX or TOOLSTATION.

CPC have a large amount of LED lamps in stock.

Isn't Daylight above Cool White i.e:

Warm White (around 3000K) > Cool White (around 4500K) > Daylight White (around 6500K)
