Thread: Radiator and AirFlow issues caused by Large Spotlights?

A couple of thoughts, Firstly I haven't had any issues with my lightforce XGTs causing airflow issues on either the Defender or the D3 that I am aware of. Secondly, the bulbs on the lightforce lights lose their efficiency and go duller after a period of time. Before you consider a light bar I'd spend some dollars on a new pair of globes. Having said that I don't reckon that the lightforces are that much better than the Rallye 2000s on SWMBOs jeep that were my old ones.

Of Course they do!

Had those 240s on our D1. When the electric fans failed on the Cape, we removed the 240s to increase airflow. That made it possible to drive the D1 all the way back to Brisbane without electric fans.
On our Defender I have fitted a lightbar instead. No effect on cooling airflow and I prefer the whiter LED light.
So I'd say go for it.

I have a pair of bull lightss, which appear similar in size to your lights, plus a winch control box in front of the grille on my 130. I wondered about the airflow but have operated in extreme heat without any problems.

I've got a pair of Fyrlyts about the same size in the same position along with a winch control box, negligible effect on temps according to my ultra gauge

Hi there was a very good video on the comparison with spotties as you have mounted and above or removed from bull bar by that fellow who does expedition videos comparing Toyotas with Defenders in Africa-- Andrew St Pierre in 4XOverland series actually proved lower temps without spotties mounted directly in front of the radiator, and this would certainly be an advantage on a 300tdi re temp issues. So lightbar above the radiator area would seem the way.

For those of you who have the large spotties mounted and reckon that there's no effect on your running Temps - Curious, but how do u know?

The normal Dash Temp gauge won't tell u or warn u of any increase in running Temp so I was wondering if u guys were running a ScanGauge of some sort that gave u a digital display...
My car came with these spotties so I've got nothing to compare to before but I guess I can remove the spotties and see if there's any difference in the SGII readings when driving. It makes sense that the BIG spotties should affect the engine running temps to some degree but would a replacing the BIG Spotties with a double row LED lightbar "in the same place" to be any different??

Apparently, LED Lightbars can't be mounted above the bullbar legally.....

I have 2 similar lights and winch control box on 2.2 130 and was worried about air flow. I noticed no difference monitoring with an Ultragauge before or after. The temp ranges between 85 and 97 deg depending on engine load. This fluctuation doesnt register on the instrument gauge and the needle remains in the middle. The higher temps are from long uphills and being too lazy to gear down not restricted air flow
