I mentored a 150w HPS grow in a chest of draws last year... buggered if I can find the link though

If memory serves, at the time I bought my CFL kit the seller also did a basic HPS kit, the only different components between the two was that the CFL kit came with an extension that terminated in a wall socket (and naturally, a CFL bulb ) and the HPS kit came with a cheap ballast and HPS bulb. The reflector and light fitting were the same, and they also sold just the light fitting separately highlighting that it was an E40 socket fitting and suitable for both - and obviously highlighting that if the intended use was not CFL then a ballast was required. I will have to dig it out and check all the details. As I said - this is purely speculative at this point.
@ M_C - Good to hear from you, dude Would love to see the chest of drawers grow! I'm guessing that you're an advocate of the micro HPS grow setup, given the choice of LED alternatives?
@Hashhound - everyone has their preferences and will shout their praises. If money, space and environment were no object then it would be all top of the range gear. I do like LED's for the compactness, but I'm starting to get interested in small HPS setup - I'd be in the interesting position where I could say I'd experimented with all three (albeit, pretty ineptly!)

Get a 250w hps and your sorted. They generate barely any heat. 2-3℃ increase at best.

It is the same E40 lamp socket they use, but the cables do tend to end in different stuff. a reflector wired for CFL will end in a 3 pin mains wall plug while one wired for HID/HPS that require an external ballast will end in one of those male sealed plastic kettle socket jobs
this plugs into a matching female socket on the external ballast and then a different cable leads from the ballast to a 3 pin mains plug, so the cables arent compatible between CFL & HID/HPS without rewiring/fitting a moulded plug or buying and wiring a new cable.....considering a basic dutch barn HPS reflector is what? £15/20? I'd be inclined to just buy one.
150w HPS used to a lot more common decades ago when it was all a bit DIY and folk were ripping lights out parks and such :P then we mostly settled into the 400/600/1000w levels with 600w being far away most popular, but in recent years a lot more 150w-250w HPS options are appearing, probably more folk getting into the hobby and wanting smaller/more efficient setups, don't see any reason you wouldn't get a decent crop from them, long tried & tested tech

Strider's Sup Lemon Haze & L.A. Confidential DWC Good...hopefully...2018
SLH & Incredible Bulk DWC Actually good, honest. 2017
i had a 50 x 50 in the attic as a little side tent and with these temps i was runnin a 400w mh

Admiral said it about right, a 250 or 400, and can use either one. I have 400W HPS in a small closet right now, no heat problems, with just a 4" fan inside, and a 9" for outtake.

As stated previously, it has the three pin male plug you show, and being a cFL kit the suppliers provided a cable with female plug at one end and three pin mains plug at the other - purely for the purposes of adapting the light fitting to work with CFL and plugging that straight into the mains. Ergo, remove the extra cable and it will plug directly into a ballast for use with HPS.
I'm going to dig the light fitting out shortly and will post some pics to show you, and yes - I will double check that I'm correct - I won't just be getting a ballast and plugging the bugger in! If it in any way represents a risk or is going to be sub-optimal, as you say - these fittings aren't expensive
Many thanks for all the input, 150W is looking like something I could work with. It wouldn't be a major change to my setup, and while I'd love to risk 250w I just got a feeling that it would require an overhaul of my ventilation tech.

Haha! Here's the little bleeder!;
Yep, it came with a kettle lead to attach this end to stick it into the mains, with lots of warnings in various languages to only use the kettle lead with the CFL bulb. It's reasonable quality - believe it's a ceramic fitting, not a cheap plastic job - presumably in anticipation of use with a hot bulb. I think it's viable. Got a reflector and hanging clips, would really just need the ballast and bulb and I have a rudimentary HPS setup all ready
@M_C - just about to read that diary now - looking forward to this!!! Thanks for finding it
