Query: Unable to keep my bonsai alive until summer.

I had purchased the light in hopes of keeping my much loved bonsai alive until the warmer weather when it thrived outside. When the light first arrived the light bulb burned out after less than 2 weeks. I think these are the type of bulbs that are long lasting. Anyway, I ordered 2 additional bulbs since there were only 2 left and I did not want my plant to be without the correct light. I am still on the first of the two bulbs I purchased next although the leaves on my tree are falling off even though I have purchased fertilizer from bonsai boy. I don't think these lights can take the place of warm weather and real sunlight. I am very sorry I am losing my beautiful long leaf ficus.
