April 23 (Reuters) - Lighting products maker LSI Industries Inc (LYTS.O) posted wider-than-expected third-quarter loss, withdrew its 2009 outlook and said it would not provide forecasts due to economic uncertainty.

Shares of the company fell as much as 10 percent to $5.36 earlier in the session on Nasdaq and were down 51 cents in afternoon trade at $5.47.

Crisis in the credit and housing markets, fall in industrial production, rise in unemployment and "roller coaster" commodity prices have hurt its growth, the company said.

"These factors have caused a substantial reduction in demand for our lighting and graphics products," Chief Executive Robert Ready said in a statement.

For the third quarter ended March 31, the company reported a net loss of $2.5 million, or 11 cents a share, compared with a net income of $997,000, or 5 cents a share, a year ago.

Excluding the impact of the goodwill impairment, the company posted a loss of 8 cents a share.

Revenue fell 27 percent to $47 million.

Lighting segment sales declined 23 percent, while sales at the graphics segment fell 38 percent.

The graphics segment, which is exposed to convenience stores, is seeing a drop in business, analyst Jonathan Dorsheimer of Canaccord Adams said.

Analysts on average were expecting the company to post a loss of 1 cent a share, before special items, on revenue of $55.5 million, according to Reuters Estimates.

"The results did not come as a surprise to us as the company is exposed to many end markets that have been hit hard by the economic downturn," analyst Jonathan Dorsheimer of Canaccord Adams said.

All of LSI's markets -- petroleum, retail, commercial and industrial, automotive -- have been adversely impacted.
