mh lights are expensive. i have used and still use the following bulbs which each retail for $70++. a 250W 14k xm, a 250W 20k xm, and some 400W 10k reeflux coralvue bulbs.

to help others save some money on their light bulbs i have just ordered 2 reefoptic 400 watt 20k mh bulbs from e-bay and am curious to see their performance. the bulbs were $40 each and $5 shipping. i will be comparing my existing (top of the line bulbs) to the new bulbs which seem to be very good bulbs.

i will let you know how they compare and possibly post some before and after pictures.

Can stand up to the xms or the reeflux? is it possible to get 2 high performance lights for the price of one??

i'll post wednesday, when they arrive.
