Compact Florescent Lights - Incandescent replacement Globes any good?

[FinnBar]

i'm really having a hard time articulating what i have in mind but here's my best shot

3 x 1450 = 4350 lm
ok, that sounds alright but with 8 Dendrobiums your grow area is pretty large. to cover that area the bulbs would have to hang relatively high, i believe
therefore not enough light reaching the plants

that alone won't be enough but as an addition to daylight they could be of use. since you have the fixture already why not give it a try.. i'd set the timers for 12hrs though and only get some 6500K bulbs.
