Here are the results. This is a kingbrite 240 watt 3000k lm301h 660nm board. 3500k board should be similar output. These measurements are without reflective walls and the hottest spot. I added the pictures with the results and a chart showing ideal ppfd range for reference.

@24 inches 25% 142 umols
@24 inches 50% 289 umols
@24 inches 100% 544 umols
