Can you have to much light?

I have a ten Gallon tall tank that I converted to a dirt tank and I bought two 26w compact clip on blue/white bulb lamps and I wanted to know if this was to much light or tha wrong kind of lights? I only have three amazon swords in my tank at tha moment and they don't look that great, now I just dirtied my tank two weeks ago so am I being impatient or do I have a problem?

It's still the wrong color temperature technically. Those color temps mimic the light corals receive deep under water in the ocean NOT in tropical waters. Tropics receive light that is best replicated by 5000K to 6700K temperature light. Yes what you currently have can work but it will but grow them as well as the correct color temp. Btw day white differs by vendor but what is needed is dependent on the application. What you have is for salt water tanks

Wrong color temperature and you need to wait for a couple weeks. You need bulbs at 5000k to 6700K temp. and no its not too much light

Too much light typically just results in a major algae bloom. You amazon swords will love a lot of light and the dirt, but as mentioned you need to get the correct spectrum. Even a 10,000k bulb would be better than the 50/50.
