Plant Grow Lights FAQ
Always, always, always, it can not be STRESSED enough, wipe your bulb down with rubbing alcohol thoroughly after any time you touch it and/or before your fire it up for the first time. The oil in your skin from your finger print can cause the glass of the bulb to heat up more at that spot and it could potentially shatter. If not it will dramatically reduce the life of your bulb. Also make sure that it is completely dry before ignition. (This is similar to halogen lights on cars) :)
Here are calculations so you may properly size your light for your circuit breaker. No one needs a fire! The formula for converting Watts to Amps is : Watts = Amps * Volts The formula for converting Amps to Watts is : Amps = Watts / Volts SAFTEY WARNING : Only use 80% of the circuit breaker capacity! Common Conversions North American and other 110 volt countries Lights : 1000W / 110V = 9.1A 600W / 110V = 5.4A 400W / 110V = 3.6A 250W / 110V = 2.3A Circuits : 10A * 110V = 1100W and 80% safe usage is 880W 15A * 110V = 1650W and 80% safe usage is 1320W 25A * 110V = 2750W and 80% safe usage is 2200W 30A * 110V = 3300W and 80% safe usage is 2640W Common Conversions British Commonwealth and other 240 volt countries Lights : 1000W / 240V = 4.1A 600W / 240V = 2.5A 400W / 240V = 1.7A 250W / 240V = 1.1A Circuits : 10A * 240V = 2400W and 80% safe usage is 1920W 15A * 240V = 3600W and 80% safe usage is 2880W 25A * 240V = 6000W and 80% safe usage is 4800W 30A * 240V = 7200W and 80% safe usage is 5760W Remember that a circuit services more than one power outlet. A two outlet wall plug will use only one circuit. There will be more outlets on 240V systems per circuit than there will be in 110V systems. Check out more information on Phillips bulbs.
1 lumens /sq. meter = 1 lux How can I convert between lux and Foot-candles? To convert between lux and foot-candles the following factors can be used: Lux =0.0929 * FC Conversion Factors 1 F.C. = 10.76 LUX 1 Micro Einstein (umol) = 7.62 F.C. 1 WATT / MTR2 = Output Bulb divided by Square meters 1 MTR2 = 10.76 FT2 1 WATT = 408 LUX 1 WATT = 37.9 F.C. |
