Philips 131W SOX-E Gear on Test/Demo Board Here is a set of gear to run a 131W SOX-E lamp. It consists of a Philips BSX 131 H96 ballast, an SX131 ignitor and a 3.4µF 450V capacitor. Note from the diagram that the capacitor connects in series with the lamp and ignitor, so is essential to the circuit. Interestingly, the ignitor is also a 3-wire type as opposed to the usual 2-wire parallel ignitor used on most SOX lamp circuits. [i][b]Before anyone comments, I am fully aware that the ballast diagram does specify a 650V rated capacitor, but I do not have one so used this one instead for testing purposes. I will obtain the correct capacitor before running the lamp again.[/b][/i] Keywords: Gear

We got a good deal on buying all of the correct gear for the SOX-E lampses. Love LPS

Honestly , the capacitor shouldn't be much of an issue for short term use . I didn't notice I had initially installed the wrong voltage cap in my Wide-Lite . It worked fine for about 100 hrs, before it finally failed . Embarrassed

That's good to know. I might be able to make up the values required with two capacitors, I'll have to check to see what I've got in the big box of caps we have.
