Ok so ma ballast has been playing up the last 2 nghts it seems that when i plug it in the bulb dont fire up rite away it takes about a min maybe a bit more, im geoin to get a new one shortly but wondering how long do u think it will last if its on its way out?

Oh n is there any danger in using this just now?

have you thought about getting a new lamp before forking out on a new ballast!! or did you mean a new lamp?

Yeah mate its the lamp not the ballast

hello dude,

Try a new bulb first before forking out for a new ballast.

SS

Ok guys cheers a've got a couple of spare bulbs there, the 1 thats in it is a Sylvania grolux but its pretty much brand new been used for bout 9 weeks is this normal for a lamp to go that quick?

No thats is not normal they should last alot longer than 9 weeks.

H.T.

A well i'll need to try another bulb later when the lights about to come on n see if thats any better

what ballast is it? i take it the lamp struck up fine before, your igniter may be on the way out, or could just be a dud lamp,lots of reports on dodgy grolux lamps.

also if you look in the lamp there's a coil of wire around the inner arc tube, this is a starting aid, so if this is broken/damaged your lamp will have trouble starting

Thats what i was thinking, but ano alot of peeps dont rate grolux bulbs either.

Its a cannatronics hydrolux ballast 400W, its only been used for about 4 grows

grolux lamps are really good when they work, it's just the 400w ones often break the starting aid, after which they don't work, or if the starting aid gets thin anywhere along it's length they have trouble starting (before it eventually breaks and wont start at all)

try another lamp and see if it's the same situation, wouldn't have thought it was the igniter as they usually either work or don't work

Will do bud light due on at 8 so post back when a've switched it on

Ok so i got a brand new bulb of a friend there that he got of ebay, this is the description they give cant find any info on the net about the company or that or even anywhere else that sells them apart from ebay, do u think this will be ok or is it worth buying a new better known bulb?

Tried the new lamp works fine must be that stupid grolux bulb wont be getting another 1 of them then only 9 weeks old n its fooked already

where did you buy the lamp from?

ebay

Should hav known better a well it was only £13 lesson learned

yeah people sell their used lamps, tossers, ebays ok, just get lamps from an ebay shop. you can tell if a lamps been used, the ends of the arc tube will be blackened, if it's brand new the tube should be clean looking al the way along and you should just be able to make out the electrodes at either end inside the tube

It was brand new mate it was of a powerseller he had like 200 of them must just have been a bad 1

I hope NEGATIVE! feedback was left!
