Bonus in attending shows, you usually pick up something, even a cough or two. I got some grain of wheat bulbs to repair my lighting on Haywards.
All now working, running off a 9V wall plug. Waste of time turning the lights on at Rail-Ex, the venue is so bright, they show no effect. But, at home in the shed, they really make a worthwhile difference. Not using LEDs, as I have to protect my dinosaur status.
