correction under flourescent lighting

[rydawg]

When it comes to flourescents, you need to have T5HO's. The biggest thing are the color temp of the bulbs. When it comes to working on paint, you need color temp between 5000K - 6500K. This color range mimics daylight to sun.

I was in a shop this year that had tons of T5HO's and I had asked the owner to turn some of them off cause I was actually seeing the defects in the basecoat, let alone the clearcoat. They made my 3000 watts of halogen seem very useless. They are the brightest units I have ever seen.

The only downfall is the price of these units depending on which one you want. They range from $150-$400.

Remember standard t8/t12 soft white flourescent bulbs will give you poor lighting and will barely show defects.

If you are on a budget and only want to replace the bulbs, then check out different color temps as an alternative.

Ya my buddy works at a electrical supply place and he showed me an 8 bulb T5 fixture, holy crap was it bright. I might have to ask him for a Christmas present.

Something like this Ryan? 4 Light T5HO Fluorescent High Bay 120V - 277V w/ Lamps - ProLighting.com

It says in the description "Replace your 400w metal halides 1 for 1. Equal light with 1/2 the cost to operate." They are that bright?

Interesting:

T5 HO/T8 vs. HID
Our T5HO & T8 Fluorescent High Bay Fixtures are specifically designed to replace conventional H.I.D. lighting in commercial / industrial applications. It's an ingenious blend of technologies as it combines the advantage of T5 and T8 linear fluorescent lamps with the mounting flexibility of high bays. The Fluorescent High Bay is an environmentally friendly lighting solution because it exceeds the demands of today's growing energy requirements.

The secret to these fixtures performance lies in the multi-faceted, enhanced aluminum reflectors that encase each lamp and focuses the output for maximum intensity. Coupled with the excellent color rendering, lumen maintenance, and energy efficiency of today's fluorescents, fluorescent high bay fixtures can be used in applications normally reserved for HID's.

Standard 400-watt metal halide fixtures rated for 36,000 initial lumens lose up to 45% of their lighting ability through depreciation and fixture inefficiencies. When compared to only a 6% loss of the T5HO Fluorescent High Bay rated for 20,000 initial lumens, the maintained lumen output is virtually the same.

A four-light 54-watt HO T5 high bay requires only 239 watts as compared to the metal halide which consumes 454 watts, a dramatic 50% savings in energy usage. In addition, the fluorescent high bay produces brighter, more even illumination with features like instant on, built-in switching and low-temperature operation.

Our FluorescenT High Bay Fixture has been designed to be Contractor Friendly by including features that make it easier to install and maintain. The fixture accepts multiple suspension methods including 3/4" threaded pipe for direct replacement of existing high bay fixtures.

Those are the ones. Good deal on those.

They are very bright. The 5000 kelvin temp is what makes them that bright and very crisp. They also put out a lot of lumens.

You'll see certain defects that you will not even see in the sun.

Thanks for the info Ryan.

Another cheap one: link

Flourescent lighting is best for water spots and etching like W/W said.

Ryan i think he was saying $400 Can, this was about a year ago and after checking the other links they must be coming down in price. The 8 bulb i think would be over kill. The 4 bulb do look interesting though. I should talk to him at Christmas as i do need a lighting upgrade.

I'm in the process of wiring the garage for new lighting, and just ordered 3 of these 4 Lamp T5's: 4 Lamp T5 Hi Efficiency Fluorescent High Bay-Lamps Included

I'll also have my 500w halogens, but these will help out tremendously.

I have noticed that the prices have come down a lot too. They are becoming very popular and most shops/warehouses are switching over to these instead of metal halides.

Did you get a chance to use these yet?
