I have never used those lights but I have a sure fire way to know. all my gear is purposefully outdated and crappy retro junk looking lol its old power compact lighting from 1999 which isn't a big deal to us planted peeps but for reefing its lol= everything is led nowadays.
so, there is only one way to know if a light can work for a pico reef, you have to locate a thread where your specific light put on coral mass. if they were able to add polyps to zoanthids, or make some candy coral split off into new growths (takes months which establishes the light in question) or if they took a little plug of SPS coral and made it base plate better, all those things
if you can't find such a thread it doesnt mean the light is questionable, it means its awaiting verification. in every tank I use, the lights I use can be found in thousands of coral and plant grow out threads. sure they run hot and terrible, but i got fanz
regarding the live sand and rock there is never just one way, and all ways can be trained to work especially if you'll just burn out algae rather than try to bio rationalize it in some way (this is why there aren't many 5 yr old pico reefs and no other reason pretty much)
this way is guaranteed to work but its not the only way, just a nice start. its the cheapest you can possibly get started in reefing.
buy carib sea arrive alive wet pack fiji pink sand from lfs rinse it off well, add to new tank.
fill up slowly w clean new sw, tank doesnt cloud because you rinsed well.
set up filter, or not (i have never used a filter on a sw tank or a planted tank, opinions vary, many do, just my opinion cuz i cut corners and costs using predictive biology)
your live rock is critical, this is a no cycle setup. I hate cycling tanks its boring and optional and very popular to do, if one elects to do so. I always opt out.
get the most purple coralline and animal covered live rock that was -aquarium cured- at the lfs for some time.
dont buy live rock from a vat that has nothing live on it. live rock is purple, the kind we use to skip cycling anyway/ make sure its not painted fake.
you tell them how to bag up and bundle the lr, do not take a back seat this is your $$
they w keep the rock wet and submerged for the trip home, either in big filled fish bags or in paintbuckets you brought. if they say to just let it sit out, opt out of that and back into telling them what to do w it
bring the lr home submerged and put it in your tank only days after you verified your heater works, the pumps work, you found the right light in a thread of no growth question.
this kind of transfer doesnt kill bacteria or animals on your live rock. your tank isn't some dangerous zone of change for them, its wonderful oligotrophic waters clean as day and the live rock simply continues on its 100 yr + journey of sitting there and being an apartment complex for little bugs, the kind we try to kill in this form (scutes=bad here, =good on reef tanks)
what you specifically have now is live sand with no life other than questionable bacteria loading, doesnt matter if there is any, it will build up in time. its the lack of organic crap in the bed you chose this fiji stuff for
the sand w populate in time w creatures from the lr and other additions in the new pico reef. nano reef, pico are 2.5 and below but nbd
so you have clean sand, clean good aerated water at 78-80, and happy lr that simply changed tanks, ergo you now have a full reef.
dont add fish yet, a 5 can handle some, but later, add fish too soon is the worst start.
get some hermit crabs and simple starter corals and begin, dont add much more until you feel better about it after reading. (this is where things start to diversify, some hate hermit crabs some dont it doesnt matter, ecosystem control is the priority, if you decide against hermits, take em back etc)
only use frozen or refrigerated high quality coral feed, you must feed the tank it cannot live on photosynthesis alone, corals are not autotrophs like plants.
the way you feed (up until you get a fish and change up all this easy balance lol) is to simply feed the whole tank weekly just before you big water change, and not so much mid week. spot feed your corals when doing this, even if they dont visually take in food (zoanthids for ex) they are still benefitting from the input and export of controlled organics in the form of feed.
there are many ways to start a reef, i do it this way to control waste sinking in the sandbed.
sandbeds are kinda 2003, many forgeo them now and just put rocks on bare bottom or arrange chunks of lr as a little rock arrangement that looks neat
the sandbed is like a diaper that stores up waste and nukes you w algae, if there is no algae plan
the bare bottom pico is much easier cleaned and exported of detritus but it looks dum imo unless you master aquascape it.
my own pico has a giant old sandbed but it can't diaper up because I change the water so forcefully, and feed only during wc time which prevents bed incursion. everybody has their way this is one that works.
