Nice post Colin, lots of good information there.
I’m liking the size of your shop . Looks roomy than 6 metres wide for some reason , as you definitely don’t look cramped at all.Hi Rick and forum members.
The shop is 11metres by 6 metres with the same on the first floor. Except the first floor is completely decked out for storage. That way I can usually keep the ground floor clear of clutter.
Thanks for your kind works on my post and I hope it encourages some of you to move to the light. In all honesty I have been using the new lights for a week now and two things hit me. One the difference in the shop is amazing with the extra light and secondly I don’t have that nagging feeling of how much this trip to the shop is costing me every time I flick the switch.
I’d certainly use them if I could, but not a prayer . The best light for me is the second least efficient,halogen . Makes sense as halogen is the closest to representing natural sunlight .Hi Rick
Sorry to here of your condition. I have never heard of this before and wish you well. As for us the reason we are always trying to reduce costs is that our utilities such as gas and electric are horrendous almost the same as having a mortgage. My son lives in Houston and I fill his tank for $30 whereas I fill my tank for $120. It’s Ying yang, we don’t pay for health care here and our insurances are very reasonable. His, is through the roof.
Not sure about Canada.
With incandescent lights the wattage of light output is also pretty much the same in heat output.The electrical savings was significant, but the real savings was due to the A/C system not having to work as hard.
Doug, I read on here someplace the other day that a TS motor wired to run on 240v has twice the hp of when it is run on 120v. I am not an electrician of any kind, but I didn't think that is the case. Can you clarify?In 1992 and 1993 I was the electrician by default on 2 old steam ships built in the 70s. Each stateroom had 3 incandescent ceiling fixtures, each with 3 60w bulbs. I had to take each one apart and install 2 CFL fixtures into each ceiling fixture, which took pretty much of my afternoon work hours for my entire assignment between the cabins, the passageway lights, and other public spaces. The electrical savings was significant, but the real savings was due to the A/C system not having to work as hard.
The newer ships are still mostly fluorescent tube, just because the initial cost of the LEDs are much higher. The High Bay Floodlights are being switched to LED, just because the bulbs are so expensive and they don't last very long with vibration.

Also when you say the LED's cost too much, I am surprised that would be considered when you think of the cost if a ship?
Thanks ,Doug, for clarifying that, And thanks for the pie chart too, I am going to copy that and hang it in my shop.Herb,
The 99% of the time the horsepower of a motor is essentially the same if it is 120 or 220v. The difference is the current that it draws. On your nameplate for the motor you should see 2 current values for the motor, one for 120v and one for 220v. The simple version of the electrical power formula is P = I x V. The way some motors are made there can be a little difference, but not a ton. A 220v motor may develop more starting torque than a 110v motor, but you probably shouldn't start your table saw under load..... The bigger issue is you can use smaller conductors to the saw, you will be able to run a higher horsepower motor for the same current. That is why 3+HP motors are 220v, and most 110v motors top out at 2HP.
As for the cost of regular fluorescent fixtures vs. LED, when you are looking at 400+ light fixtures it makes a noticeable difference on that line item, and that is what the specifiers look at when pricing a ship. Usually the ship builder has a very limited range of choices for the customer, because they want to make as many carbon copies of the same ship as they can. There are a lot of differences of opinion I have with how ships are outfitted, because it never seems that lifecycle costs are taken into account. What is cheap to build may be very expensive to maintain.
Apparently they aren't considering operating costs either since the saying that nothing is for free is universally true. More wattage to run inefficient lights means more power = higher fuel costs to generate that power. Pretty basic physics.Herb,
