1000w hps globes

[wayno1]

hey everyone,

 

 

i'm currently running a 1000w hps wich i've had for a while, thinking of changing the globe for the next grow i can get my hands on some son t 1000w hps globes for free brand new. now the question, would i be better of getting a grow specific globe or going with the son t do they have the same lumen/lux output

 

cheers

a few weeks ago i bought a digital light meter to test my son-t 1000w hps globes. i had just bought 2 brand new ones and wanted to test the lux difference between the new ones and the ones that were almost 3 years old. not even 10% difference.

 

also, i use son-t euro globes. i thought son-t meant extra blue. ive now been reliably informed that is b/shit. son-t is the european acronym for sodium tube. same spectrum as other 1000w hps globes apparently.

 

but the euro verions of the hps globes apparently had a higher lumen output than the american. although with the latest hight output american sunmanster and growlush hps apparently pushing out 150k + initial lumen, this advantage may be no more.

 

how long have you been running the 1000w hps globe you have now? is it a euro or american hps ballast?

Hey there lefty,

 

what sort of lumen output are you getting of the son t globes, i have had my current globe for about 5 yrs and used it for about 9 months of that mind u i got it second hand so it could have been thrashed for all i know..

 

will it be written on the ballast if its yank or euro

 

i put the son t in my grow rm before and it was dull as fuck compared to my old one, the old one is a sylvania luma lux,

Don't forget lumens only measure light in human eye response terms, so you're not necessarily getting similar outputs from new and old globes even if the lumens appear to be similar.

 

It should be written on the ballast, yes, but not always. One other way to tell is if it has amp figures. A euro ballast will use more amps on start up than running, (AKA reactor control ballast) and a Constant Wattage ballast will use less on start up than running. You can't use a CW globe with a EURO ballast though, it won't ignite.....

 

If it's a horticultural bulb, it'll grow plants well. But I'd definitely change 1000w lamps every 9 months minimum. The difference in growth can be astonishing from one crop with an old lamp to the next one with a new one....

hey there wayno

 

just go the son T mate thats what i use in me 400w and they do great not shore about the 1000w ones but should be fine

 

cheerz :Dj:

heres a pic of the luma lux globe and sonT the luma luxs filament is considerably bigger,

if you are running the Osram Nav-t/Son-t lamp u have the 1000w HPS euro control box u can only run one type of lamp on that gear that i know of thats avaliable in oz i used the same light a few years back and the filament is like the 400watters compair a Phillips Son-t to a Lucagrow and you will see the Lucagrow fillament is alot longer its actually as long as a 600 watter

if u are unsure what type of control box u have and its not printed either remove the cover or look thru the vent it will be printed on the ballast
