Floodlight upgrade

[StamfordBee]

I noticed in the Colchester programme that the floodlightlight rating is being upgraded to 550 Lux. Does anyone know what the Lux value was before the upgrade?

 

[Carri Bee Un]

I don't, but a little bit of me is going to be thrilled to find out :yes:

I'm glad I asked the question then

:yes: 12.5 Lux just ask FarnhamBee

 

[David Brentford]

I didn't buy the prog on Tuesday - when did it say the upgrade was taking place?

 

[TW1Bee]

Before the upgrade I think it was equivalent to four 60W pearl light bulbs bought in Somerfields in 1995.

I was reading in the Gateshead programme about this. Apparently floodlight bulbs should be 500 odd lux but after time they dim. The League of Wales top rofl clubs have been told they all have to upgarde to 550 lux. The bulbs cost 160 quid each.

 

[jharvey85]

Will they be de-Lux? :worm:

1 lux!

They are low energy ones so they take a while to get to their full brightness!

Some time before the World Cup squads fly in to use Griffin Park as a training pitch

I thought we'd have an answer by now. I am in some distress. The GPG is failing

The answer my friend is blowing in the wind, but Griffin Park was noticably brighter last Tuesday night.

I agree

Lux not been too good recently. Perhaps a new set of bulbs will help?

only one bulb left that needs replacing, it's a difficult one to physically change but we'll get there ! :yes:

I'm sure abee is up for the challenge, after all if dear ol' Percy used to do it...

He's up the ladder trying to sort it for us all as I type ! :love2:

Still no definite Lux figures though fans kept in the dark etc etc

It's probably on the Charlton web-site !

[Inappropriate Smilies Bee]

and Bagpus was just a saggy old cloth cat. But Emily loved him.

get rid of that silly brook road stand and that would give us at least 20 minutes of extra light in the autumn.

why are they called floodlights anyway?!!?? they should be called darklights or football lights.

:bling:

Need to bring 8 mates in to pay for one bulb

Like our players on Lucozade

Still if the players don't dazzle you the Lights will roflroflrofl .........unless we all get

Didn't they used to be measured in candle power before someone invented lux?

The Candela, which replaced candlepower in 1948, is the measurement for the power of light, whereas Lux is a measurement of illumination of light. Think of Candela as the amount of light output, Lumens are the amount received at a point and Lux as light covering a square area; Lumens per square metre. So Lux is the correct measurement for floodlights.

Rather sadly, I originally worked in Optical Metrology...

As good as the explanation is,could you please put that explanation into laymans language please.

I never realised candlepower was replaced as long ago as 1948!
Thanks for shedding some light on the subject

Candela/candlepower is the amount of light coming out of a bulb in a specific direction - it's a measure of output but pretty meaningless in terms of everyday use.
Lux is the amount of light from a bulb that falls onto an defined area at a defined distance; it's a measure of illumination. So, it's much more of a useful measure for determining how a bulb will light a room or a pitch.

Simply, candlepower is how bright it is when you look at it; Lux is how bright it illuminates something else.

I shall certainly see things clearer from now on

Maybe you were thinking of Gaslight, I can remember a house in W4 still using them in the 50’s.

My Grandparents house in Hounslow still had gas light in the late 50's.

Really dangerous set up.You first opened the gas tap fixed to the light,struck a match and lit a small cylindrical object, made of something like gauze, called a mantle.
It flamed and then glowed to give light.

Imagine the Health and Safety police of today dealing with that.

Can Mr Tree help? No ladder required!

Thank you for that,which certainly gives a very clear explanation of some very complex information, but also interesting when expained like that. Thanks jlove
