Hi guys ,
Can anyone suggest me good lighting for my planted tank.. the tank dimensions are 90*45*50 cm .. the plants are going to be variety of mosses.. crypts cuba , cababomba , frogbits, ferns. No co2 dosing as of now. And fauna shrimps, neon tetra and rainbows. Has anyone tried sanrise aqualover leds, btree leds or rio reh led. Which of those are economical or any other leds or t5 and place to buy in chennai ?.

I'll give you a very economical solution. But it is guaranteed to work.
Go for CFL bulbs (cool daylight, 6500k temperature). These guys are so underrated in the hobby.
Calculate how many you need based on the lumens they give out, not wattage. For good plant growth you should aim for 50 lumens per litre. So for your tank you need about 10,125 lumens. Buy your CFLs accordingly.
No need to delve to much on giving a varied color intensity. Just give the natural 6500k and let the plant decide which color intensity it wants to absorb based on its growth stage; that's what they do in nature right?
I have setup a couple of tanks with lush growth based on this principle. Had first done this for my uncle's tank. Was a bit skeptical at first on how it would turn out. But in 2 months the growth was astounding. Then I tossed out my Hitachi aquarium t5 lights and installed CFLs @50lumens/litre for my 100L non-co2 tank. Results are great.
Just make sure that during the initial period you also plant some plant that outcompetes algae, till your primary plants set in. I like Indian fern (Ceratopteris cornuta) for this. Though in your case the cabomba will also play the same role.
