Lamp Replacement

[WantDaChronic]

i have 2 lights int he same grow room, 1 is slightly newer than the other but missed being used on one of the grows that the other shined upon...anyways, the one that hasnt been used as much starts off a shit load more blue and stays that way for alot longer than the older one...the older one starts off in a deep orange colour and then works its way to being more blue.....

 

the old one should be getting replaced in a month or 2, but globes can be pretty expensive, especially when on the dole and you dont make money from weed :thumbdown

ive been using the same 4 x 1000' watt euro's in a G-room for over 2 yrs. same yield as when i first got em. so doesnt make much sense to me to replace - at least until either the yield drops or the globe stops working i used to have a theory that the guys selling these things were just making us change em to make em more money.

So I am assuming metal halide is a HID and I should replace twice a year? I see a lot of HPS talk and just wanted to makee sure the same applied to MH.

Yes, HPS & MH are both HID lamps :thumbsup !

Agree with you perrye75, let them keep glowing as long as they can efficiently.

 

1000w, I had one with a 'glass growth' on it once after about 12 mths, discarded. Another wouldn't fire up, half way thro flower (ALWAYS have a SPARE globe) , discarded.

One now is at the end of about 2 years straight 12/12, no probs.

 

 

Thanks for chart sydneyguy - 24000 hrs, sounds right yep.

just to add another point, did u know that the euro 1000watters put out more lumens than the american ones.

 

also, i recently 'blew' a couple of 1000watters (accidently plugging a euro hps into a mh balast!). replaced 2 globes with brand new ones, which were run side by side to 2 x yr old 1000 watters. and the results were same sized buds, same yield etc. no difference.

i had a euro hps 1000watter what a peice of shit after running for 8 hours it would hum first 8 hours it was nice and silent

gazza i would say it was more likely a one off 'fault', of the ballast perhaps. i have 8 euro ballast and they only 'hum' as much as any other ballast when they first turn on... then there fine. however, i would say that the 'new' ballasts on the market now are definitely quieter than the old style ones that ive had for about 10 yrs+
