Thank you that would be handy, you can probably tell I've never done this before

I'm probably barking up the wrong tree entirely, but have come across induced voltage problems before, which seem to have been caused by a disconnected cpc, 90-100V in one case. Have you checked the cpc?
Limited choice on the packaging front. I'd probably go for this given your 2K2 Ohm choice: Buy High Power RESISTOR 50W 2K2 Vishay RCH50S22000JS06 online from RS for next day delivery.
Easy to solder some lugs on for use and wrap in heatshrink for use. Should be easy enough to incorporate in the box(es).

Burnt out? What did you use as a heatsink?
Power at 25°C | 50W with heatsink, 5.5W without heatsink |
Resistance Tolerance | ±5% |
Temperature Coefficient | ≤1Ω ±250ppm/°C, >1Ω ±150ppm/°C |
Operating Temperature | -55°C → +125°C |
Thermal Resistance | 1.0°C/W |
Limiting Element Voltage | 1285Vac |
Overload Voltage | 2500Vac (Max.) |
Dielectric Withstand Voltage | 3.5KVac |
Insulating Resistance | 10000MΩ |
Length | 50 mm |
Width | 29.4 mm |
Height | 15 mm |
This is getting silly.
The customer has low energy lighting, 2 X 7W was mentioned. To stop the slight glimmer a loading resistor is suggested which if we go with the first suggestion of 2K2Ώ which will dissipate about 19.5W of waste heat. Near three times the lighting load.
It’s making a mockery of “energy saving”.
Would it be possible to fit a single halogen somewhere in the circuit? At least it would do something useful.
