Answer: 
In order to answer your question, I would need to know the total wattage of the 8 lights.
If the total wattage is less than 1500 watts, then yes it will do the job. If your total wattage is more than 1500 watts, consider changing some of the out to LED lights to get the wattage down and then it will work.

Answer: 
The EJ500 has a maximum load rating of 500 watts and ONLY works with with incandescent lamps (can NOT be used with LED flood lamps), so the flood lights would need to be (a) standard incandescent, and (b) 60 watts each or less. The model ST01 timer, however, has a maximum load rating of 1800 watts (which would allow using eight flood lamps up to 200 watts each) and works with LED bulbs as well and would Read More

Answer: 
Yes, as long as the total wattage on the timer is less than 1500 watts. If it isn't, then consider changing a few bulbs out to LED lights to get the wattage down.

Answer: 
Yes, the timer's load rating is within the circuit rating so this is an appropriate configuration.
Please note that the EJ500 is not compatible with and cannot be used to control lighting transformers, compact florescent bulbs, or LED bulbs and can only be used with incandescent bulbs with a minimum wattage of 40W.

4-Amp In-Wall Astro Digital Timer is rated 4.3 out of 5 by 21.
Rated 1 out of 5 by from JUNK Horrible device. Display is nearly impossible to read (I had to try using a magnifying glass). Programming is convoluted to the extreme. The computation for Sunset is very general which caused me to have to 'game the system' by mis-setting the actual time to get the lights to come on before dark. Once set, it worked well for a number of years, however, when I wanted to change the programming, it failed to respond to commands, would not reset to factory settings. I bought a replacement unit made by a well respected electronics manufacturer and have been delighted, it is everything this piece of junk was not: easy to program, back lit, easy to read with normal reading glasses, has a precise computation for sunrise/set based on your Latitude and Longitude.

Pore outages do not effect the settings. The installation is fairly easy, but the initial programming was time consuming. It would be much better to have instructions for a quick initial set=up. This devise has many set up options that require extensive programing. I just use the dawn to dusk option for my front and rear porch lights.

Rated 5 out of 5 by from Perfect I used this to light my front porch garage lights. I tried several and all have failed including the wifi lights since they require to be wired to the neutral bar. This was easy for me to program and fit my schedule and can accommodate either a single pole or 3 way light switch configuration.

Rated 4 out of 5 by from Versatile timer with back up battery This replaces a front yard timer and is the same as my back door timer that I have had for several years. It has worked well. My only objection is that it is very tedious and somewhat confusing to set the program but once done, it works well and does not lose the program in power outages.

Rated 5 out of 5 by from Great Digital timer Great switch. Used two in our previous home for nine years, on had to replace one battery. Programming is easy when you get used to the sequence. No need to remembering to turn your lights on or off. I use it for my outdoor lights.

Rated 5 out of 5 by from Works great Easy DIY wiring took less than half an hour. Programming is a little tricky but only took a few minutes - included directions are good though you may want to read through first before you start. I programmed the time to use the astrological clock for our porch light and it works perfectly. I have not adjusted programming since initial setup despite power failures to house. Works exactly as advertised. Great switch!

Rated 4 out of 5 by from Something you need to know The timer was easy to install. I used it to control out some out-door lights. However, there was a problem. When the timer was off, one of my outdoor lights flickered. It took a $90 visit from electrician to discover that this timer does NOT work with the CFL light bulbs I had. When we changed the bulbs to incandescent everything worked fine. So I think there should be a big warning to tell people just what type of light you can use with this device.
