that's a very interesting subject. i have mostly tropicals indoors and some go out to ultra bright NE balcony outside. lots of variegation. i think indoor culture is quite different from outdoor and season to season and latitude - just all very complicated! what i found is that a lot of time recommendations for these plants are from southern growers ... for outdoors! (FL). bright shade in summer in fl = bright dappled sun on the window sill for me in NYC. seasonal light differs a lot too. so while i put my plants in some early sun, NE bright shade(no sun) outside in summer, in winter they stay in dappled sun west window or even full sun west. one example is crotons: early summer outside in 3-4 hrs of sun cooler temps is great! but then they really color up in october too - no direct sun, 60-65F. while hot temps over 80F and direct hot sun in july -aug totally bleach out the leaves. but indoors west partial 3-4 hr sun in winter does wonders for them. caladiums are similar to that. they green in too much shade and bleach out in too much hot sun. while take 4-5 hrs of direct eastern sun indoors in summer. i have many more: stromanthe triostar, alocasia african mask, etc - that are strictly indoors. they are supposed to be in bright shade only, but i keep them all in dappled , even direct early/late sun to maintain color/good growth indoors in winter and sheers filtered sun in summer.

If it is only on a single circuit look for a multi-wire circuit. This is a pair of 120 V legs feeding two circuits. The two legs share a single neutral, and if the neutral becomes disconnected then the 120 V between the legs can move around depending on exactly how much load is on each leg. What happens is that the two 120V circuits are acting as a single 240 V circuit. If the loads on each side are exactly the same, the midpoint stays at ~ 0 volts. If the loads are not exactly the same the mid-point moves away from 0 volts. Multi-wire circuits may have a common trip circuit breaker, but not all are required to. If you do not understand how they work, or are not comfortable working n a panel board, call an electrician. You should avoid using the two circuits.

The fixture look very nice, but the tubes are probable expensive.There are shades like that available here, made in china that you can use with 2 feet long t5's.

OSHA says minimize glare! For example, if lighting is excessive or causes glare on the monitor screen, you may develop eyestrain or headaches, and may have to work in awkward postures to view the screen. Arrange your office to minimize glare from overhead lights, desk lamps, and windows.
