How Many BTU's per 1000 Watt Bulb?

[GR33NL3AF]

Come on. With properly placed wall fans you can go 3k BTU per 1000w or 3500 BTU per 1000w w/ CO2. I have a 2 ton system successfully cooling 6000w w/ CO2, no vents or glass. The room has a 3 degree swing at most. It's all about fan placement.

I have always used 4000btu's per light and I run CO2 also. I have 8 1000w in a 2250sf room (15x15x10) each light is in a cool tube and I run a 1 hp chiller to cool everything.
I have 2 50" ss chiller coils and my DIY cooling rad for this room in the summer when temps are 95+ my room stays at 80 to 85. Here is a pix of my chiller barrel with the rad. Got the rad for 20$ brand new from auto wrecker.

I see a lot of posts on how many btus but what about brands of ac and where to get them? Would this system do the trick for two rooms with 6k in each room heres the link looks like an easy install too. Ductless

I like the idea but sounds like a shitty unit, you can do better than 13 SEER.... Search for Cannabis John, the HVAC pro who commented on the first page. He has a thread on here dedicated to answering questions just like this.

Well for anyone that does not like to estimate or guess, 1 watt = 3.412142 BTU/hr. (Look it up, its a fact)
And Watts = Volts x Amps (Also a proven fact!)
Look at the nameplate on your ballast. Read the amp draw or FLA (Full LoadAmps)
If ballast is outside of the room multiply the FLA amps times the efficiency of the ballast, or just multiply by 85%
Measure the voltage supplied to your ballast.
Ballast inside room ...BTU/HR = 120 volts x 10,0 Amps (nameplate) x 3.41 = 4,092 btu/hr
Ballast out of room... BTU/HR = 120 volts x 10.0 amps x 3.41 x 0.85(lowefficiency) =

Typical non digital ballast not in room>>>> 10.0 Amps x 120 Volts x 3.41 x 0.85 = 3,478 BTU/HR
Typical non digital ballast located in room>>> 10.0 Amps x 120 Volts x 3.41 = 4,092 BTU/HR

So.. Ballasts in room....4.1 times bulb wattage = btu/hr for lights
And ballasts outside of room....3.5 times bulb wattage = btu/hr for lights

Ballasts in room 4,100 btu/hr for each 1000 Watt bulb (for non vented fixtures)

Ballasts outside of room 3500 btu/hr for each 1000 watt bulb (for non vented fixtures)

This is only to remove the heat load of the lights. Additional cooling will be required for other heat sources in the conditioned space. If the heat source is due to an electrical device you can estimate the cooling load with the simple formula
1 watt = 3.41 btu / hr

I run 8 1k de,(ballasts outside room)and a 14000 btu burner on a 3 ton ideal air 18 SEER in a 14x16 and I will need more ac come summer.the dehumidifier is what puts me over the edge.

Need some help guys we got a 3000 square-foot building there’s gonna have 8o-1000 WAtt lights trying to figure out the tonnage or a/c for this building I live in Oklahoma high Humidity
