ballast

Was going to lay membrane on a small external storage cupboard and gravel over with 20mm shingle/gravel. Then I started cleaning it up, removing the loose from the ground and it turned out to be more than expected and so am looking for ideas. Need to fill the voids with cement/ballast mix to...

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!

Context: - This fixture is daisy chained and this stopped working (with new tubes / starters) a few months back. The subsequent fixtures in the chain are fine. - I opened it up and checked with my voltage detector that the current is entering but not leaving the ballast. - I bought an LED tube...

I have a T8 ballast to replace in my strip light. I took it down hoping to replace it with exactly the same part. However I don’t seem to be able to locate the particular one that’s in there. I’m not sure which spec I have to be careful to match to ensure it’s the best alternative and make...

I have a 2D florescent bath lamp which is constantly blinking and won't remain switched on. Tried replacing the start switch which made no difference. I want to try replacing the bulb now to see if that's the problem however i don't know what type of ballast I have and most of the bulbs i've...

Hey guys, I need some assistance in wiring a G23 Uv bulb with a 9w magnetic ballast on the attached pic. Totally lost with how to wire it. There's 4 connections from the ballast. Not sure which goes to the bulb and which goes to the mains. I have also read online that I would need to earth the...

As per attached photos. Do you reckon this is a mix of Gravel 20mm or just ballast? I would need to match the mix to back fill a trench. Thanks

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...
