hps=high pressure sodium mh=metal halide both are high intensity discharge lamps or hid these types of lamps emit alot of heat and do need to have both high exhaust and intake to replenish the co2 in your grow room you will need more than one to grow decent sized plants one will not do i suggest buying hid over leds since they emit heat and can be better controlled than leds i did not get very good results with this light and bought an hid in its place and sold this one on ebay

Hell if i know. The only thing i do know is that HL stands for high lumen & DS stands for dual switch.

Sorry, I don't know. I suggest you either check with HP or see if you can find out on line.

The R does stand for Radial but to be honest nowhere in our book does it say what the H is for, but it is definitely not just for right.Thanks,Tires USA

"NP" stands for Nitro Piston technology. It is easier to cock then the spring loaded version. BTW, the 30131 shown is not the shorter version. That would be the NPS.

While these switch housings look identical I have never seen or touched a HP33 Hydromatic. Therefore, without the actual dimensions of the gasket and bolt holes one cannot be sure. Question is why not by the parts from Hydromatic?

Much more efficient than HPS, even to run two of these units to replace one 600W HPS only uses about 340W.Plus think about the energy costs you will save on cooling and ventilation, HPS is HOT, LEDs are at their worst warm.

The item i recieved is HP Model ATSN 7001044-Y000 Rev:B Series HSTNS-PRO1 Build:0C SPN 403781-001. It appears to be identical in form, fit, and function. One of the two that i purchased has been in service since the middle of January.

The brand is Harold Import Co. The stamp on the bottom is blue and contains the initials H C, with the outline of a wire whisk between the H and the C. Underneath the initials, it states "Harold Import Co." I have enjoyed the pots. They are well made, sturdy, and very attractive. I recommend them.

The MH is for vegetative growth then switch to HPS for the flowering stage.

I don't recall the "H" designation on the ones I bought. I do know the designation for the 13 rechargables will say "mH" to show it is metal halide composition. Some will show "N" for nickle cadmium composition. F.Y.I. when I buy rechargable batteries for any application in my house I always prefer MH over Nickle. They last longer and take more charges for me.
