I have an unfinished 2-story detached garage (20x24). First story is the garage and the second story is a studio like apartment. I am considering using recessed lighting on the first floor. I understand that the ceiling is a fire barrier to protect the occupants on the second floor. One sheet of Type X 5/8" is rated for 1 hour and two sheets of Type X 5/8 is rated for two hours.
Any penetrations though the ceiling degrades the ability of the fire-barrier (ceiling) to be effective. I searched for Fire-Rated Recess Light Housing and found Cooper Industries Halo (H750FR2ICAT). So I go to Womack Electrical Supply (WES) Website to order one. It says: "Your Price $240.00 each". That does not seem right.
Anyone know of any reputable resellers willing to sell to a Por-DIYer like me? HomeDepot / Lowes do not appear to carry any product like this in my area. And I prefer to do business with local shops when I can.
Side Question: Do the resellers like WES even want to do business with the likes of me (Pro-DIY).
Revised base on "Lee Sam's" Answer:
Area = Pi * r(2).
Area (6" hole) = 28.27 sq inches
Ceiling Area = 20 ft x 20 ft = 400 sq ft
4 * 144 sq in / 28.27 = 20 each 6" holes.
I suspect I will only need 12-16 each 6" holes for recessed lights.
After further thought, I still would want to install light fire-rated recessed lighting housing or some other method. My kids might be sleeping in the second floor one night.
I am also evaluating creating a recessed channel between the i-Joist within the gypsum board to install lighting.
I liked recessed lighting in a garage with 8 foot ceiling because I want to avoid the glare and I want to keep from hitting a light fixture with a 2x4, plywood, pole, etc. If I had 10 foot ceilings, I would just mount the lights on the ceiling.
Revised: July 21, 2020 Garage lighting needs/requirements/brainstorming.
- General Lighting: Soft Lighting (3500K-4000K color range) will automatically turn on with enough light so that the family can get into and out of the car safely, move around the garage, etc. The general lighting would would be on a motion/sound sensor and turn off automatically after 20-30 minutes. (I found a brand/model used in my office at work).
Note: When the garage door opens, I don't want there to be so much glaring light flooding out of the garage that it looks like an alien invasion (like "Close encounters of the Third Kind").
Party Lighting: More Soft (3500K-4000K color range) lighting that General Lighting for a birthday party, family gathering, covered space for BBQ, etc. I would clear out and clean the garage for this type of event. Setup of food tables, etc.
Work/Task lighting: This would be a third set of lighting that I can turn on as needed for working on the car, small wood working projects, kids school projects, etc. The color of this type of lighting would be in 4000K-5500K range. Unsure about the amount of Lumens (or how bright) needed.
