yes two bulbs are good. all you need is to check the color temperature of the bulb. In my set up, I have one bulb that is 6500k and 5500k. CPs appreciate light on the bluer end of the spectrum.

Do you mean you will run 2 on 12 hour cycles and the other 2 on an overlapping 14-16 hour cycle? If by safe, do you mean will they burn your house down? They should not. Flourescents do not generate a lot of heat. Personally, I run a 1000 watt Metal Halide lamp for 16 hours a day in my house (yes, the electric bill sucks....) and have no problem. As long as your fixture is good, you should be fine*. Personally, I would not run it for less than 14-16, especially if you are using t-12 or t-8 lamps (the thick shop lights).
Take a look at the t5 fixtures while you are at it. They cost more but I think they are worth it. My Nepenthes Vetricosa is under a t5 and really seems to like it!
*Note: If you are ever in question about the safety of your setup- talk to a professional electrician or other qualified individual. My advice is very general in nature and should be taken under advisement.

i am going to put 2 2 bulb grow lights "4 footers" in my window hightwise facing the window so that the lights are on end in the 2 sides of my windows i am going this will not cause my plants to grow to the sides but if this is the case then i will put a stronderlight suspended above them so they will grow up... i will be running the timers for 12 hours a day and see how they grow i am buying the nights later today but at the moment i only have one one bulb there with a cutting under it to see what happens.... does anyone know how many lument one of these bulbs put out??

if the leaf become light yellow with some red dots, the answer is no. You should try.
The wavelength of light is most important. color tempature is not.
some study point out that wavelength for plant should use 660nm red light and blue light. But those plant are not nepenthes, does anyone have experience with led light in Nepenthes? Also someone say that 630nm for plant is good too. I am a bit confuse about those information.

LED lights work very well, some of the exxagerated efficiency claims are BS but they are a bit more efficient than flourescents. You need a mix of red/blue and maybe orange or white. 660nm is the peak absorbtion for one type of chlorophyll but ive used the cheaper 630nm leds and the plants grow fine, 660nm might be more efficient i've not tried them. A big difference with LEDs is they give of less heat into say a terrarium so you may need to add some daytime heating! Some rooms in my house are now lit with LED daylight bulbs and they use only a few watts to light an entire room!

Greetings,I've worked in hydro industry 25 years Now.let me simplify the matter.You generally what to give a plant about 5-10,000 lumens.I would stay with neutral color bulb 4100k otherwise known as cool white.5500-6500k lack red.But generally any bulb between 3000k-6500k works great.When bulbs say something like cool white plus.It means that its colored corrected spectrum.Lumens is more important than Kevin color.I personally use 1000w digital hps.It puts out 150,000 lumens.I use hortilux bulb with 28 cri .Led,s work great too.If using Mh Setup.sunmasters bulbs is the best bet.Just stick with t8 lights.stop stressing and enjoy the plants.Sean

HPS are good to put your house on fire. I recommend HO T5, i got 4 of those badboys, 4.5K lumens each (3ft, you get 5K lumens with the 4ft) They are cheap, No heat, No electrical problem. Best Lumens/$$/no heat ratio, for a Nepenthes You need AT LEAST 12K Lumens (for an adult) Mine are growing well with the 4 T5 sunblasterlighting.com/lamp-and-fixture.php << (about 30CAD / 3ft) I mean if you are a serious grower maybe you can eventualy use HPS, but leave that for the Marijuana Growers

I have to beg to differ on the HPS being a good way to burn down your house. Yes they do get warm (I run a 1000W MH/HPS convertable in my house) but if set up properly they are pretty safe and do a darn good job! Is it possible that they could burn your house down? Yes, but usually in the past this has been traced to faulty ballasts and/orbad setups. Consult your liscenced electrician if in doubt. Given the choice, I would take a MH over T5s anyday. I am not sure if T5s really have the best $/linens/energy ratio. You very well may be right but I seem to recall the 600W HPS taking the gold on that one.
If you are going to go HID, I would choose MH over HPS for carnivores. HPS is very red. Not a bad thing but carnivores are usually cultivated vegitatively (ie not brought to a flowering cycle on purpose which is when red light is very handy).
T5s are definitely not a bad way to go. As was mentioned it is much easier to manage heat under T5s. Also, since you do not need to cool them with a duct fan, it is easier to manage humidity (or rather keep it higher). I have an N. Ventricles under my 4 bulb T5 fixture and it is growing like a weed right now.
Both are good options.
