Led Lights

I would say it is on the blink. ;=))

Are you sure you've bypassed all the electronics, not just the starter, in the Flouro system.

They should be hooked directly into your 12 volt power. Providing it is 12 volts not 240?

we have to get this straight.

There are different products designed for different applications.

There are LED fluro replacements designed to go directly into 240V fittings.
In this case you need to do exactly as the instructions say.

When you say"bypass" the starter what do you mean.
It occurs to me that most of these 240V LED fluro replacements simply require the starter to be removed...that is a different thing to being bypassed.

The starter activates the heaters in each end of the fluro tube and causes a striking voltage from the balast when it opens......none of this is required for LED.

If it is a 12 volt fluro replacement.....that could be a straight forward 12 volt LED array.
The original 12 Volt fluro would have been driven by an inverter....that is a different thing to a starter.

If you have a 12 volt fluro that is running an inverter and you are putting a 240V LED fluro replacement in that fitting, you may have problems because most of the inverter fluros do not operate at 240V and 50 Hz as a conventional fluro does.

You need to know what you have.
