430W bulbs?

[Guest]

How can I tell if my 400W ballast can handle a 430 Agrosun red?

I used a 430 watt bulb Philips Son-T agro with 30% more blue spectrum light during veg n early flower on a 400 watt regular ballast (brand: Cecla)..no probs

I bought my ballast online... its kind of ghetto.. literally says "budget grow lamp" on it.

i dont wanna see it implode.

Oh I see.

I would NOT risk it then...safety always comes first:

Always match the lamp type/wattage to the ballast.
For example: 400 watt lamp should not be used with a 1000 watt ballast. Although the ballast may ignite the lamp, it may cause it to explode, or, at the very least, reduces the life of the lamp.

I heard that a HPS bulb exploding has the power of a hand grenade

Yea, eff that noise.

But then I get thinking buy a better ballast.. and then the obvious next thought is .... bigger???

I wonder if I can vent a 600W in a C25 well.

its fine,...it just wont power the bulb to it full potential,...i use old 430sonagro bulbs all the time in my 400watter,...and atm im even running a 360watt(rated for a 400watt ballast) conversion bulb in my ancient 430w diamond ballast,..i was worried about an under wattage bulb in a higher power ballast but no problems so far,..goin over a year now....

So I should be ok to run a 400 hps with my 430 diamond ballast?

First off, take note of details, these guys last posted on this thread nine years ago.

That said, as HPS bulbs age they begin drawing more power and putting out less light for it. Eventually the bulb will light but cannot sustain the effort and goes out within minutes.

With this variable power usage built in to the ballasts any rating within 10% is good to go.
And for horticultural use the bulbs need to be changed every year even though they will continue to burn for five years and more.

Yes I know it's an old thread but I thought it better to search and post in a related thread compared to starting a new thread.
Thanks for the info on the 10% range.
