Studio Lighting Led Bulbs To Replace T-8's

01 August 2015 - 12:16 PM

I read an article in home power magazine about LED florescent tubes. They bought them on e-bay to replace T-8s for about $12 each.The t-8s draw 46 watts the led use 20 watts.
I have a boat load of t-8 fixtures in 4 and two bulb configurations.
Since then I have replaced about 9 fixtures most in studio and some in kiln loading area. I still have about 5 left to do but am now testing them. They come is warm and cold lights and clear and striped (diffused).I have mixed some warm and cold in the studioand the light quality is good . Outside kiln area I want the most light so I chosse the 6500 clear bulbs. These are all plastic lens and are made in china. They say 50,000 hours.
These bulbs operate on 120 volts and you need to cut the ballast out of the circuit. So one end of fixture wires to the nuetral the other end wires to the hot wire. You can leave the ballest in place or remove it.These tend to be brighter or as bright as the t-8s.In our area we have expensive power so this will make sense in the long run-within two years the bulbs will be close to free..

1227 Element Burned Out

28 July 2015 - 05:18 PM

Well after decades of bisques my #2 element toasted at the pigtail. This old rust bucket has good bricks so I ordered a new element-the other elements appear to look good.I'm not a skutt fan but I'm looking to nurse a few more years on this old kiln.I bought some quality stainless screws to reassemble as skutt uses junk hardware which rusts out very soon.
Next kiln will be an L&L.

Overfired Gas Kiln Today

15 July 2015 - 10:24 PM

Well this happens even to the old timers. I was loading my car kiln and a firing my small 12 cubic gas kiln to cone end point cone 11.
A friend came over to help work on my 250 hp outboard fuel system ( extremely complex )I checked kiln and cone 10 was almost down with a stiff cone 11.
I walked away saying I have to set a timer to remember as my head will be in the replacement of all fuel pumps in complex outboard system.
Starting loading up tools for job and spaced the timer and the kiln. Later my helper came out and said the cone was gone and I had that oh my god feeling. Turned off kiln without looking in. I will know on Friday what it looks like the digital pyro said 2500 even-the most its ever read.
I had glazed the whole load for a hot fire but not this hot. I'll follow up on friday as I/m firing car kiln all day tomorrow .
I feel like a space cadet now-its been a decade or more since I have done anything close to this.I'm glad the whole load is on advancers as glaze will not stick to them.
