  We present a comprehensive analysis of observing a light Higgs boson in the
mass range $70$ -- $110$ GeV at the 13/14 TeV LHC, in the context of the type-I
two-Higgs-doublet model. The decay of the light Higgs to a pair of bottom
quarks is dominant in most parts of the parameter space, except in the
fermiophobic limit. Here its decay to bosons, (mainly a pair of photons),
becomes important. We perform an extensive collider analysis for the $b\bar{b}$
and $\gamma \gamma$ final states. The light scalar is tagged in the highly
boosted regimes for the $b \bar{b}$ mode to reduce the enormous QCD background.
This decay can be observed with a few thousand fb$^{-1}$ of integrated
luminosity at the LHC. Near the fermiophobic limit, the decay of the light
Higgs to a pair of photons can even be probed with a few hundred fb$^{-1}$ of
integrated luminosity at the LHC.
