This is the most cost competitive LED fluorescent batten solution.
Don't bother to pay an unreasonably high price for those integrated LED Battens;
Don't bother to pay huge for the rewiring;
These fittings have already been pre-wired for LED tubes and they come along with ONE 9W LED tube. So you don't need to buy led tubes for this batten.
The body of the batten is aluminium, which makes the batten not only light but also highly resistant to the salty whether of New Zealand.
