Lightbulb help.
Im looking for advice on lightbulbs.
Lastnight the LED bulb in my bedroom decided to pack in, it was a 43watt bulb. Today to replace it thinking the lampshade was max of 100watt where its 60watt i bought some halogen classic bulbs to replace it which are 100watt = 129watt. Now i know the reason they put the max wattage on lampshades is because of heat, my question is will it be ok to put a new bulb with existing lampshade? The new bulbs dont give out nearly as much heat as the old bulbs this is where im confused and asking. Thanks. |
Re: Lightbulb help.
If the bulb wattage is too high the lampshade could melt if it's made from a plastic material, or potentially catch fire if made from material.
I would get a different lampshade. |

I agree, you can buy LED light bulbs up to 150 watt equivalent now with consumption of 10 Watt. |
Re: Lightbulb help.
OK thanks guys.

I would suspect that the 129W value is the light equivelent of a standard bulb compared to the halogen. The 100W will be the heat equivelent.
However I'm steadily replacing all the conventional bulbs in our place with LEDs as they fail. If you need something that looks like a conventional bulb, especially in fitments that need that sparkley effect then consider LED filament bulbs. These are available in a number of styles including antique immitations like this: Attachment 27343 |
Re: Lightbulb help.
My LED bulb average 60 watt is not nearly as bright as my older type
|
Re: Lightbulb help.
My 11 watt LED bulbs rated A+ are far, far brighter than old fashioned type 60 watts, but they are expensive. Let's hope they last as long as they claim.

Re: Lightbulb help.
The figure of merit for any lightbulb, irrespective of technology, is the Lumen. As a guide a standard 100W filament bulb emits about 1600 Lumens. This is the total light output of the bulb.
Scale as appropriate and select your LED bulb accordingly. I've had some really good bulbs from Lidl under the Livarno Lux brand. The Narrow beam GU10 dimmable reflector ones are rated at 5W but are a perfect replacement in colour, brightness and beam for 50W halogens. These have 3 LEDs with colimating lenses in front. |
Re: Lightbulb help.
Home Bargains have been selling GLS style LED lamps for a while now. I have all my chillie and strawberry seedlings under the 100w equiv ones, and the whole house is now bright and cheery.
9w (60w equiv) 806 lumens daylight (6500K) £1.59 12w (100w equiv) 1500 lumens daylight (6500K) £2.99 They sell both bayonet and Edison screw versions. |
Re: Lightbulb help.
I bought a 10watt = 60watt LED in Wilko, its not as bright as my old bulb which is gonna be a pain as i use my webcam to skype so im gonna have to use a lamp to.

Re: Lightbulb help.
Whilst we are on the topic of bulbs and there seems to be a few knowledgeable people here.....I have one of these which uses a 300W dim-able, giant edison screw, incandescent bulb.
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? :) |
Re: Lightbulb help.
Wilko sell dimable LEDs not as high as that though.
Try ebay or amazon? |
Re: Lightbulb help.
Look on Amazon plenty of dimable bulbs... ES = Edison screw; ESC + Edison Small Screw.

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? https://www.cableforum.uk/board/atta...1&d=1521378354 |
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. |

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. |

From my mate's shop... but probably better suited to a lighthouse :D http://www.green-lamp.co.uk/product/250w-cfl-bulbs/ or use this type of adapter to use standard E27 bulbs http://www.green-lamp.co.uk/product/...light-adaptor/ |

I was about to buy that but then I noticed that it weighs half a kilo! I think I'll get the adaptor and then the world is my mollusc as far as light bulbs go :D |

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

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. |

Warm White (around 3000K) > Cool White (around 4500K) > Daylight White (around 6500K) |
Re: Lightbulb help.
Sorry my mistake. the mid colour can go by a few different names.
DAYLIGHT is probably the best for household use. https://www.toolstation.com/shop/Lig...0+Lamps/sd2681 http://cpc.farnell.com/c/electrical-...lobe-led-bulbs https://www.theinternetelectricalsto...l--led-9-c.asp All the colours..? https://www.theinternetelectricalsto...our-1728-c.asp |
Re: Lightbulb help.
I think it all depends on what you're used to as to which works best.
My view is that if you're going from Incandescent or most CFL bulbs you're probably best going for Warm White bulbs as these are roughly the same type of light. Cool White and Daylight have their uses but have more blue light in them, so aren't so good if rooms you'll use in the evening as they'll feel a bit harsh. |
