Another one in the history books was a great show and attendees looked to be enjoying themselves for the weekend.

Re capital cost.  We just went through the process. For lights that are on 9-5 5 days a week, payback was 6 months.
Your numbers may vary this by a bit I suppose, but for us it worked out like this:

2000lm LED tube (there are many, many cheap, crap, low output tubes out there, avoid them) $20
Measured power saving per tube 30W
Price of electricity $0.38 / Kw hr

That's assuming that you do it all at once. if you wait for the old tubes to fail then your effective cost is a little less because you were going to buy a replacement tube anyway.
We went the whole hog and removed the ballast and starter from the lights to scavenge a few extra mW

We've backed this up with our energy monitoring system which shows us saving about (but just under) the amount we expected.

From the title, I thought you wanted a fluorescent handle on the starter :bow:

So where does Methyl Hydrate fall into the alcohols discussion? I've been mixing shellac with this for a few years now with success. It's available pretty much everywhere in Canada. Gotta keep our fishing huts warm in the winter ya know!  :thumbup:

You can color shellac pretty easily with a variety of different dyes that are commonly available. TransTint is one brand name that comes to mind, it can be bought in liquid form. I'm sure that I've also used powered dyes from Lee Valley in the past also. I think with the correct amount of dye to shellac to alcohol, it would make a durable layout fluid as the OP suggests.

Very good Andrew.  :thumbup:

Last time I changed mine I bit the bullet and bought electronic starters for them all.  I've not had to replace any yet.

 - pig ark sheets are not only too curved, but have insufficient reach - I have a couple here unused at the moment. No grain silos unfortunately - the nearest one has been converted into a letting holiday home  :clap:

Presumably stress cracks, but whether from original casting or the repeated heating and cooling in use I wouldn't want to say  :scratch:
Tools / Fluorescent Starter Gripper
« Last post by awemawson on April 23, 2018, 02:54:10 PM »
My workshop has a lot of twin 6 foot fluorescent fittings, many of which are mounted quite high. (I know I should replace them with LEDs but the capital cost is horrendous !)

I find extracting and inserting the starters extremely difficult, especially when perched high on a ladder on tip toe! The problem is that very little of the starter protrudes, and reaching it you have to reach past the tube which sometimes has proved impossible. I've tried various bodges to grip the starter but none were satisfactory.

Today again I had to change a starter so I decided to solve the issue once and for ever. All the starters I've come across have two dimples in them, presumably to engage a special tool, but I've never been able to source that tool :bang:

So - you've got a 3D printer - print one  :ddb:

Didn't take long and the result makes the job SO much easier  :thumbup:

Today the cladding arrived, and I managed to get the front (window side) and rear clad. The rear needed a bit of size adjustment as it was not square.

Then the new floor went down

I did have probing enabled with no probes connected. Disabled it in config - hope this fixes it and thanks for the suggestions!
