hi,just wanted to check before i wire up an e40 fitting i just purchased.the fitting has two wire clamps but no markings,are they just like a normal household bulb fitting and doesn't matter which way around the live and neutral wires are attached?

Yes mate nice and simple.

G.A.T.I

cheers for that.just wanted to be sure.

NO They MUST be wired correctly for SAFETY reasons
Live is in the centre Nuetral is the outer connection
If you wire them anyway you like you can make the outer ring of socket and lamp live

JS is correct.

do not wire it any other way than, live to centre and nutral to outer.

HPS are not normal houshold bulbs, they have an igniter in them, if you wire it the other way round the ignitor might not fire, or even explode the bulb.

thought i'd best add some pics to avoid confusion.[attachmentid=101520][attachmentid=101521]

give us a pic of the top m8, and we will point out the correct pins for u.


btw that looks like one from the online leccy wholesaler, if it is then they are pretty rubish.

just watch the pins when u are tightening the screws up, they have a habit of bursting off the interior parts.

Sorry andyr1rider i just assumed it was for an enviro and mine worked fine

I should have asked what it was for.

Glad you're ok

hi burstbud,do you require a pic of the inside to clarify?

no problem gati. too old to have spiky hair anyway these days

yes m8, that would help as there are quite a few going around.

here's the pics.[attachmentid=101525][attachmentid=101527][attachmentid=101528]

Sorry again I'll pop back and see the answer as i have another 2 to wire up and must of been lucky with the first



G.A.T.I

connect the live/brown to what is the middle/centre contact
which is the part that you see in the"bottom" of your first new pic

TB

so am i right in saying that i connect brown/live to the middle sprung connector and blue/neutral to the outer c shaped connection,looking inside.

yep

here ya go.

hope this helps

thanks for all your help everyone
may the ganja gods bless you with big buds aplenty

Remember to screw the bulb in TIGHT, to do this get some kitchen roll or toilet paper and wrap it round the bulb, then screw it in tight. And I mean TIGHT!

DO NOT TOUCH THE GLASS WITH YOUR HAND, the grease off your fingers will cause a hot spot on the glass and make it more susceptible to explode.


Not screwing it in TIGHT will cause your ballast to get really hot

thanks for that.some good tips there

but not that tight or u will break the holder or the bulb, only hand tight

i got a 400w hps, do i need a ballast or can i run it directly through a switch, to the plug socket?

dont wanna fuck it up from the start

You will need a ballast to power the lamp, and also a contactor if you want to use it with a timer.
