Im not entirely sure. Cheato doesn't need insane amounts of light, but It might need more then that. Google "magnetic refugium light" Its a 4-LED fixture which will magnetically attach to the back of your glass. If the 4 LEDS that you have will put out as much light as those 4 then I would say you are probably good to go. Is there anyway of hooking them up and just trying to grow a little cheato to see? Its pretty cheap stuff and if it starts to die you may want to try to increase your lighting by either supplementation or possibly a new fixture. You can get grow bulbs and a fixture from like home depot or lowes for really cheap prices and you would be good to go.
