I would forget what the lights are labeled as, the power draw is the lights wattage, thats the number you want to use for comparison. 40-50 watts/sqft is a good rule of thumb and from your post I gather you are working with 35 square feet so 1400 watts would probably be fine. Good leds will generally perform better than hps or cmh lights with the same wattage but as Aquaman said the price of entry is much higher for leds. With your budget in mind I also agree that cmh or hps would be the way to go, they will be worth the money which is more than can be said for some of the cheap leds out there.
If you do decide to go the led route, amazon does not have the best deals in this category. Good leds will usually start around $1/watt and will have full spectrum white light (most of your selections were full spectrum), not several multicolored looking diodes that make blurple light. You want the light to be in the 3000k or 3500k spectrum for the best results if you are going to use it in veg and flower. Kingrbrite, a seller on alibaba has inexpensive leds that have been highly praised by many growers here who can also confirm that it at least uses fairly high quality up to date parts. I have experience with Timber and
HLG, both of which have worked very well for me but will be a little pricier than kingbrite. If you start with cmh or hps you can save up some cash for next black friday as
HLG tends to have some pretty great deals.
Oh, and you will probably be dissapointed expecting a pound per plant. Its not that it cant be done but it is difficult not to mention its usually more practical and efficient to grow a larger number of smaller yielding plants. How long you veg the plant, the genetics, environment, and many other variables will play a bigger role in your yield than what kind of light you are using. If you have anything less than a perfect setup and can get over a gram per watt you are doing pretty good.
