ballast

Hi all. I need to build a small concrete pad 224cm x 86cm x 10cm for a new bin store. I always find it hard to calculate ballast and cement for concrete which I need to get to grips with. Can somebody help me work out my materials please? Thank you!

Having replaced the 2D bulb in a kitchen wall light and finding it still didn't work, I'm trying to fit a Tridonic PC 1x26W BASIC ballast. This replaces the original ballast where the bulb plugged directly into it which I'm told is no longer available. However I can't get it to work when I...

Hello Please excuse this newbie question, but I'd like to replace the gravel/ballast on my garage roof which is flat with a slight slope. The smallest gravel they sell at my local DIY is 10mm pea shingle, but the gravel I am replacing is much smaller, here is a photo comparing each of them...

Hi all. I recently bought a ballast to replace the one in my bathroom serving a 2d light fitting. The existing (black) ballast is shown below wired up. I ordered the white one thinking it to be a straight replacement (2d fluorescent, single fitting, 26W). I did look to the manufatcturers website...

Hi, got a Osram T8 ballast to install. Could someone please tell me the type of tool used to insert the wires to the terminal and/or a link to one to see it? I thought it was idc type but that doesn't fit. Unbelieveably I cannot find decent inf on the net about the type of tool to use. Thanks...

So today I did a little experiment and thought I would see what would happen if one powered up a 70W HPS bulb with an internal ignitor directly on the 230v mains without using a ballast. Sadly not much happened other than a brief flash for a fraction of a second before the MCB for the circuit...
