Here we have 2 x Labcraft - Transtrip 12v inverters for 8w fluorescent lamps

You will receive TWO lamps with this listing

 
Each one will operate an 8 watt 12 inches (305mm) fluorescent lamp from a 12v battery (as used by campers, caravanners, boat owners etc.)

Connections: 6 way terminal block, battery positive, battery negative and 2 connections to each end (cathode) of lamp.
Dimensions:
3 inches (78mm) long
1 inch (25mm) deep
2 5/16 inches (58mm) overall width

CAUTION - Polarity protection. Labcraft-Transtrip 12v inverters for 8 watt fluorescent lamps incorporate pcb fuses and are marked on the pcb underside with minus and plus signs and the 6 way terminal block carries a red mark at the end adjacent to the positive connection.

WARNING - Users must always ensure that the polarity of the 12v supply to the inverter is correct, otherwise damage to the inverter will occur. These inverters do NOT incorporate polarity reversal protection.

Original equipment manufacturers (OEMs) are advised to include a polarity protection feature between the inverter and the input feed terminal block of their equipment. eg a suitably rated blocker diode.

Free postage for the UK and low cost postage for overseas.

This listing is for two units and I have more available. Please also see my other listings for many more light fittings and lamps. Thank You


YOU:

Hi,
Thanks for your message. I am glad they arrived safely. I do not have a image to help with connectivity, but have previously found something similar online. I am aware the top connection is positive and the bottom connection is negative (for the 12v supply) which is important to connect correctly. Then the four contacts in the middle are for connecting the four pins of the lamp. If they are connected incorrectly, the lamp does not work (but is not damaged), if correctly, bingo, it works.
Hi,

Thanks for your kind answer.
I did some experiments, knowing that it would not damage the hardware.
Here is what I found: for short tubes like the 8w 30cm, you only need to connect one wire to each end of the tube (contact 2 and 4, or 3 and 5, both work)
Connecting the four is required for longer tubes in order to heat the starter filament which in turns start the lighting of the tube.
Not needing this, I stayed with only 2 wires for each tube which works perfectly for me. 
Thanks a lot.
Best regards.
