Hi Guys

After bit of help on this one please.... pricing to replace some church lighting.

Currently have in place 250watt sodium wall lights, curved up/ down style (I'll try an attach a picture of something similar.) Ceiling height is around 8 metres, lights mounted at around 5 metres from FFL.

Want to get an LED equivalent, which I've been told is around 100w LED.

They want to keep same sort of style as gives good back ground light.

Thanks Sy

i'd have thought 50watt LED would be as bright if not brighter.
 
Definitely Sodium? If so the colour temperature of the LED fittings is likely to be vastly different.
 
Remove gear and install corn lamps, if fittings are in good condition.
Just done that in a church. Light levels much higher from existing up lights, as required. Get warm white.
100w led is equivalent to about 400w metal halide.... or sodium, I suppose. Just make sure you've got room in the fitting, especially around the lampholder.
 
Colour will be nothing like the sodium lamps make sure they are warned it won't be such a warm colour churches can be picky
 
Thanks Guys for all the pointers...... was going to go for a 3000k if so, and more than likely rig up a sample on plug top to show them first.

Never heard of these Andy, do they come back up on/ full temperature instantly after switched off? Thats why they are getting fed up with sodium (as well as running cost.)

Corn lamps are LED, so no they don't have a startup time.

Changing to LED of equivalent light output won't change the running costs much, and if you don't get very good quality LED they may even increase power consumption for the same light output.
Sodium lamps were, until quite recently, more energy efficient than LED.

Honestly it is all down to the colour tempreture and the lumen output , if you are lucky enough to find the spec of this sodium on it is very easy to get near like for like.... he may need to change all as lighting can look odd if different in various locations. :)
