If you're super tight on spending for lights, a lamp like that can work if you tilt it. What you need to do is feel with your hand how close to the bulb before it feels TOO warm, and don't be tough about it. With a 13W bulb like that you can literally suck on it (please dont)... lol.. because its hardly warm at all. Sorry drank 4oz of potka. Nasty shit. Anyway, buy a splitter for bulbs, its like a Y adapter socket. $1 to $2 probably. Whatever bulbs you use, be sure you don't exceed the rating of the socket. I mean, that lamp you show will be rated for max 60W or 100W. With Y splitters you can get carried away and overload the lamp itself. Use at least the 23W/26W bulbs if you can, not the 13's. Having two 23W "daylights" for veg is the most minimal, in my opinion, and nobody should waste their time with less. For flower time, you really need to figure out how to get AT LEAST 250W in there of the 2300-2700K "light temperature" range, to make it cost effective. Also research how to maximize the use of light (scrog, topping, FIM, etc) and getting large roots with a good size planter, and proper use of nutrients. Its a huge subject and fairly well documented throughout this server. Lots of questions are reposted like mad, I started posting here about 2 months ago after having successful ops in the past, and am surprised at how many reposts there are. Seems like these are becoming frequently asked questions and something better could be put in place to link these threads or something. You really need to research thoroughly, use the search function its your friend.
