Is the Bluewave ballast made by Sunlight Supply not Son Agro? I always thought it was.

Sunlight Supply and PFO both had the "Son Agro" style, also called HQI 400W.
The 400W HQI PFO "Son Agro" style was actually a 470W ballast.
The pictured dual ballasts you have should say " BW-7 DUAL 430W MH HQI" on the label. Please check if that is the case.

That won't quite run them as hot as the PFO will, so that makes sense that you are not exploding them. A VERY good thing... exploded MH bulbs are no fun.

Still baffles me using HPS ballasts with MH bulbs. Yea both are similar sometimes.
One of the problems that I can see with the ANSI code system for American HID lamps is that it leads us here to think that any lamp used on a mismatched ANSI code ballast will ALWAYS burn out instantly even though a certain pair of lamp types has similar voltage and current such as 150w M102 metal halide and 150w S56 high pressure sodium.

Finally completed a list of the ANSI ballast codes:

Mercury Vapor
40w – H45
50w – H46
75/80w – H43
100w – H38
100/125w – H44
175w – H39
250w – H37
400w – H33
700w – H35
1000w – H34
1000w – H36

Metal Halide (Red's Probe Start, Rest's Pulse Start)
20w – M175
22w – M130
35/39w – M130
50w – M110
70w – M98
100w – M90
150w – M102
175w – M57
175w – M152
200w – M136
250w – M58
250w – M153
320w – M154
350w – M131
360w – M165
400w – M59
400w – M155
450w – M144
750w – M149
875w – M166
1000w – M47
1000w – M141
1500w – M48
1650w – M112


Double Ended Metal Halide
70w – M85
100w – M91
150w – M81
250w – M80
1500w – M133
2000w – M134

Low Pressure Sodium Vapor
18w – L69
35w – L70
55w – L71
90w – L72
135w – L73
180w – L74

High Pressure Sodium Vapor
35w – S76
50w – S68
70w – S62
100w – S54
150w – S55 55v
150w – S56 100v
200w – S66
250w – S50
310w – S67
400w – S51
430w – S145
600w – S106
750w – S111
1000w – S52

Yes indeed, I agree.

The conventional wisdom has been if you overdrive 400 watt Radiums their useful life is shortened to around 6-8 months. Given that mine are only being overdriven to 430 watts and not 470, how many months do you think I could get out of these if I run them for 7 hours a day?

I would use them for a year. I use other bulb for 2. Don't mind a bit of degradation enough to replace them sooner.

It looks like we can still get the radium 400 watt bulbs, for now. I like them better than the Hamilton 14K.

Hamilton Lighting website. I ordered 400 watt radium 20K bulbs earlier today. They're there. Go get 'em while they're in stock, lol.

Postponing the LEDs yet again, yay.
