as I have bin given these without the light unit itselve, I gust had in mind to put them on a pendant ore so.

proublem is, thy bothe cant fire up a phounix bulb, while thy are for regular DE HQI lights.

is there a way to mesure a ballast to check if thy are ok?

could it be that the coralive units have some sort of capasitor build in the unit to fire up a bulb (ax I might be missing this than.

it is gust fustrating to have the ballast sitting in a box, where I could use them.

any input?

This message assumes your ballasts are magnetic ones

The DE bulb is a pulse start one (there are only two main probes in it) and not fired by a capacitor or by a subprobe but by an ignitor.

In your case, the ballasts built particularly for the coralife fixture have no ignitor in it.

The ignitor is in the fixture.

You can check by opening the metal box to take a look. If there is 3 items in it, then the smallest one with 3 wires ( usually green, yellow and red) attached to it is the ignitor. Otherwise you need to buy an ignitor (one for each ballast.)

Most of the time, the ballast between 70-150 watt uses the same ignitor.

Use the phase like "150 watt mh ignitor" to search on ebay or google.
