MH Bulb Replacement

[Limpc]

Hello all DIY gurus,

I got a ATMAN MH 150W. Recently bought a Arcadia AQI 150W 14K bulb and replace. But it does not fire up. Only can see arc of light betw the electrodes of the bulb. Incompatible ?

Anyone has similar encounter.

Appreciate your generous advices.

Did you check for loose wire connections in the set? I had this problem with my light set previously.

I have this problem before. U need to

1. Clean the metal contact. Carbon built up due to arcing

2. Tighten the screws of the bulb holder. Overtime, the screw will become loose and contact will be loose. As such u cannot fire up the MH.

Thanks, guys.

From the replies, electrically the ballast/ignitor should be compatible with the Arcadia lamp. Will do the recommended measures as stated.
