I have a set of RPS lights like the ones in the photos. It uses old style blue colored light bulbs with aluminum reflectors. The light stands are very good. I'm thinking about replacing the entire light heads (with the reflectors) with the new styled multiple-socket light heads and light boxes. The old head just used one light bulbs and the bulbs are too hot on anything or anybody.
This is for shooting still pictures of products now. May expand and include light portrait work.
Any suggestion what I should get? Prefer to keep it within the budget and no plan to get a full blown studio kid yet (even though that is not a huge amount).
The modern equal are large(ish) 'compact' flourescent that are daylight balanced in thier gas mix.
With them there is no need to filter out the bulk of the lower temperature tungsten emission spectra with the blue filtering to just pass emission of the daylight balanced portion of their spectra.
Then there are also banks of daylight balanced LED's coming to market in the theatrical lighting business. I have not looked to see if they have crossed into the photo lighting spectrum. The LED emisions are very spiky, so colour balance is likely not daylight balanced withthe theatrical LED's yet.
I am not into studio work, but I have noticed that there seems to be a number of studio lights available over here that use banks of LED's. They run very cool and are close to daylight quality.
I see most of the new studio light kits are multi-bulb heads that use new type spiral bulbs. I should get a couple of them. Just not sure if I need all the light boxes, etc....
Fotodiox makes a series of lamp heads that take multiple bulbs. They're square grids with 16 sockets, and there's a less powerful version with I want to say 9, but I don't remember (I have the 16). They're not expensive, and output a tremendous amount of light. I would recommend getting some kind of light control device with them, like a softbox with removable front diffusion panel, because otherwise they spill light all over the place.
The biggest 'compact' flourescent I have seen recently in a photo retailer looks to have three u shaped tubes that connect to one base.
The base is quite wide before it tapers to the meduim screw shell section.
So while it may screw into the socket you have, it's base may be too wide for the throat of the old hot light reflectors.
I'm thinking of keeping the socket and replace the bulbs only, as someone suggested.
If I'm going to change the sockets, it may be better to replace the entire head, with umbrella or light box.... I think they are better than the reflectors I have. But I prefer to keep the costs down for now.
