A: Thanks for your query!
Can you clarify your question, - "I do see that the VT10 emits twice the light" - this is incorrect, HappyLight models VT10WW1 and VT05FWW1 are roughly comparable in output, so it really comes down to which form factor most appeals to you. Both items are very suitable for use in an office environment to supplement scarce natural light.
If you are referring the HPLD HappyLight Deluxe, then yes, this is a large device that puts out a lot of light, and it might not be the best product for someone new to light therapy, or for use on a desk in an office.
